The doctrine of the Holy Trinity, which states that God is One in three Persons – Father, Son and Holy Ghost – is central to our Catholic faith. This awesome teaching is so far beyond human understanding that it could only be known through revelation.
Yet as lofty and mysterious as it is, the doctrine of the Holy Trinity does not contradict our reason, nor totally elude our grasp. The great St. Patrick, when evangelizing Ireland, made the mystery “palpable” by using the humble shamrock, with its three leaves on the one stem, as an example.
Thus God is a pure, eternal, omnipotent and omnipresent spirit with one nature and one substance, but three distinct persons, the second of which, the Son, became man to redeem mankind from the original stain of Adam and Eve.

Scriptural Examples
Whilst
the triune nature of God was known in the Old Testament, the clarity
with which the mystery of the Holy Trinity is revealed in the New
Testament is truly remarkable.In St. Luke’s Gospel (1:35), the Archangel Gabriel says to the Virgin Mary: “The Holy Ghost shall come upon thee, and the power of the most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God.”
At Jesus’ baptism in the Jordan, it is the Father Himself Who gives witness to the Son: “And lo, the heavens were opened…And behold a voice from heaven saying: This is my beloved Son, in whom I am well pleased.” Matt. 3:16.
And while Jesus often speaks of His Father to His Apostles, He also distinctly mentions the Spirit to them in such passages as John 15: 26: “But when the Paraclete comes, whom I will send you from the Father, the Spirit of truth, who proceeds from the Father, he shall give testimony of me.”
Later, as Our Lord commands His disciples to spread the Gospel throughout the world, the triune nature of God shines forth in full splendor in the baptismal formula He entrusts to them: “Going therefore, teach ye all nations: baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” Matt. 28:19. Notice one name but three persons.
Even Satan, while tempting Him in the desert, endeavored to pry from Jesus His true identity: Was He the Son of God? Matt.4:3, 6.
The Trinity Attacked, and Defined, through the Centuries
Throughout
the history of the Church, the doctrine of the Holy Trinity has been
challenged by multiple heresies. Thus, as early as 259 AD, Pope Saint
Dionysius was already defending the Trinitarian doctrine against the
heretical errors of Sabellius who held that God had three “faces” or
“masks” rather than being three distinct persons within the Godhead.One of the most extensive declarations of the Church on the Blessed Trinity dates from 675 AD and was issued in Toledo, Spain, at that time in the throes of an Islamic invasion, whose Koranic claim branded Christians as idolaters because they adored Jesus Christ as God.
In 1213, in face of the Albigensian heresy which believed in a good and an evil source to creation, the Fourth Lateran Council defined: “We firmly believe and profess without qualification that there is only one true God, eternal, immense, unchangeable, incomprehensible, omnipotent, and indescribable, the Father, the Son, and Holy Spirit: three persons but one essence, and a substance or nature that is wholly simple.”
Thus has the Church defended, and defined, the Trinitarian Dogma down through the centuries and into modern times.
Our God, not Distant, but a Friend
And so, through divine revelation and the definitions of the Church’s Magisterium based upon this same Revelation, we can know who our God is: one in substance, three in personhood, eternal, creator of all things visible and invisible, all powerful, everywhere present.
But such an awesome Creator is not distant from His creation. Our God is Love, and Love, by its very nature, is communicative. A marvelous aspect of the doctrine of the Holy Trinity, which has inspired and drawn the saints through the ages, is what is called the “indwelling of the Trinity”.
This
doctrine teaches that not only is God present everywhere in a general
way, but with those who keep His commandments, and live in His grace, He
establishes an intimate relationship.Our Lord Jesus pointed to this “indwelling” at the Last Supper when He said: “I shall ask the Father, and he will give you another Paraclete to be with you forever, the Spirit of Truth whom the world can never receive because it neither sees him nor knows him; but you know him, because he is with you, he is in you.”
And just so we don’t think the Spirit alone dwells in us, Jesus clarified: “If any one loves me, he will keep my word, and my Father will love him, and we shall come to him and make our home with him.” John 14: 16, 23. So, not only the Holy Spirit, but the Father and the Son dwell in a soul keeping “His word”.
The indwelling of the Holy Trinity begins at Baptism and continues so long as that soul remains in God’s friendship and grace. Serious sin “expels” this presence, but can be regained with repentance, and a sincere sacramental confession.
Just as with any other relationship, we can grow in friendship with our three divine guests by prayer and the practice of the Christian virtues. The saints took this friendship all the way to deep union, a state that gave them uncommon love, joy, trust and fearlessness in all they did, even the gift of miracles. This divine friendship is offered to each and every one of us.
Indeed, the doctrine of the Most Holy Trinity is central to our faith, and our awesome patrimony.

Rita
was born in Roccaborena, Italy in 1381 to aged parents who were known
for their charity, and who fervently thanked God for the gift of a
daughter so late in life.
Christopher
Magallanes was born in 1869 in the province of Guadalajara, Mexico, of
devout parents who were poor farmers. As a youth, he worked as a
shepherd, but felt called to be a shepherd of souls. He entered the
seminary at nineteen and was ordained at the age of thirty.
Bernardine,
“The Apostle of Italy,” was born on September 8, 1380 in the Tuscan
town of Massa Marittima. His father, a member of the noble Sienese
family of Albizeschi, was governor of the region.
In
1417 his fiery eloquence burst forth, inflaming the souls of the
multitudes. He preached fearlessly in cities large and small rebuking
evil in places high and low. After hearing him, penitents of all classes
flocked in droves to the confessionals. His great devotion was to the
Holy Name of Jesus and as he preached, he would hold up a plaque with
the initials "I.H.S." an acronym for the name of JESUS, and had people
place the Holy Name over the gates of towns, and over the entrances of
their houses and businesses. Pope Pius II who listened to Bernardine in
his youth said that people listened to him as to another Apostle St.
Paul. Tirelessly and on foot, he traversed the length and breath of
Italy, launching a true moral reform.
St.
Dunstan, most famous of the Anglo-Saxon saints, was born near
Glastonbury of a noble family closely connected to the ruling house.
St.
John I was a native of Siena in Tuscany and was one of the seven
deacons of Rome when he was elected to the papacy at the death of Pope
Hormisdas in the year 523.
Paschal
was born in Terra Hermosa, Spain on Pentecost Sunday, May 24, 1540 the
son of Martin Baylon and Isabel Jubera, pious day laborers. The feast of
Pentecost in Spain being called “Pasch of the Holy Ghost,” the child
was named Paschal.
Once,
when Paschal was sent on a mission through France, which was then
undergoing fierce religious convulsions due to Calvinists and Huguenots,
he bravely defended the doctrine of the Eucharistic Presence against a
Calvinist preacher, barely escaping with his life afterwards.
St. Isidore the Farmer, patron of Madrid, was born of poor parents and named for St. Isidore, the Archbishop of Seville.
Saint
Francis de Sales, the bishop of Geneva, while on a journey during Lent,
went to the church attached to a monastery of Capuchin friars.
The
Greek name “Matthias” means “gift of Yahweh”. All we know for certain
of Matthias is that he was chosen by the eleven apostles to replace the
traitor, Judas, after the Ascension of Jesus and before the descent of
the Holy Ghost on Pentecost, which makes St. Matthias the only apostle
not directly chosen by Our Lord.
The conversation developed in the following manner:
"It
was upon saying these last words, 'the grace of God...' that for the
first time she opened her hands, which emitted a most intense light that
penetrated our breasts, reaching the innermost part of our souls and
making us see ourselves in God, Who was that light, more clearly than we
can see ourselves in the best of mirrors.
Most
of what we know of them comes from an epitaph written by Pope St.
Damascus: "Nereus and Achilleus, the martyrs, joined the army and
carried out the cruel orders of the tyrant, obeying his will continually
out of fear. Then came a miracle of faith: they were suddenly
converted, gave up their savagery, and fled the camp of their evil
leader, throwing away their shields, armor, and bloody spears.
Professing the faith of Christ, they were happy to be witnesses to its
triumph.” By these words of the Holy Father, we can understand what
great deeds can be brought about by Christ’s glory; for, being once
participants in the persecution of Christians themselves, Nereus and
Achilleus knew perhaps better than any other Christian what pain awaited
them. However, faith triumphed over the fear of death, and the victory
of faith was the sweetest victory they had ever known, this time as
soldiers in the army of Christ.
Showing
early signs of intense piety and intellectual ability, he was received
into a community of secular priests who initiated his education. He
received the tonsure at sixteen and was ordained with special permission
before the age of twenty-four.
St.
Damien is known as the Leper Priest and the Hero of Moloka'i. Born in
Tremelo in Belgium on January 3, 1840, he was son of a farmer and his
wife. He lived a devout life and in 1860 obtained permission to join the
Congregation of the Sacred Hearts of Jesus and Mary. Although born
Jozef De Veuster, the young brother took the name Damien in religious
life. In 1864, in answer to his prayers to St. Francis Xavier, he was
sent as a missionary to Honolulu, Hawaii. Here he applied himself to
diligent study to compensate for his lack of an early education, and he
was ordained to the sacred priesthood on May 21. For the next nine years
Fr. Damien worked in various missions throughout Hawaii.
Wishing
to do more to help God’s suffering people, Fr. Damien volunteered as a
missionary priest to the leper community on the island of Moloka'i. His
offer was accepted by Bishop Louis Désiré Maigret, the Vicar Apostolic
of Honolulu and on May 10, 1873 Damien was formerly presented by the
bishop to the flock of his new mission.
The
Hero of Maloka'i died of leprosy in the early morning of April 15,
1889, at the age of 49. After his funeral Mass at St. Philomena's the
next day, the whole leper colony of Moloka'i followed the funeral
cortège to the cemetery where Damien was laid to rest under the same
pandanus tree where he had slept upon his arrival at the mission.
Magdalena
was born on March 1, 1774, into an ancient and prominent family of
Verona, Italy. She was a descendant of the Countess Matilda of Tuscany
outside whose Castle of Canossa Emperor Henry IV of Germany did
penance in 1076, in submission to Pope St. Gregory VII who had
excommunicated him.
Upon
their return, Magdalena began a work to assist the sick and the
wounded, particularly girls and those left abandoned. On several
occasions, the young Marchioness hosted the conqueror Napoleon Bonaparte
who, impressed with her work, granted her an empty convent for her
enterprise.
John
was born in Harpham, a village in Yorkshire. As a young man he joined
the famous school of St. Theodore in Kent, where he distinguished
himself. Later, he joined the Abbey of Whitby in his own country, where
his exceptional abilities marked him out for preferment, and when the
diocesan see of Hexham became vacant, he was appointed its bishop.

Phillip,
seemingly a disciple of John the Baptist, was the third apostle, after
Andrew and Peter, whom Christ Our Lord called to follow Him. A family
man, St. Chrysostom says of him that he still found time to meditate on
the law and the prophets, which study prepared him to recognize the
expected Messiah. Mentioned several times in the Gospel of John, we get a
glimpse of the Apostle Phillip as a man of an amiable, earnest and
circumspect disposition.
James
called “the lesser” because he seems to have been younger than James
the Greater, was a brother of John and was also known as “James the
Just”.
Athanasius,
known as “the Champion of Orthodoxy,” was born in Alexandria in
approximately 297. Nothing is known of his family except that his
parents were Christians and that he had a brother, Peter.
The
embattled bishop was accused of everything from exacting a tax on
church linen to killing a dissenting bishop (very much alive in hiding).
After these accusations, his life was plagued with harassment,
banishments, the need to defend himself before councils with periods of
reprieve depending on which emperor reigned. At one point his diocese
was even usurped by an Arian bishop. Five times he was driven from his
post, spending a total of seventeen years as a bishop in exile. When
banished, Athanasius followed the example of his friend St. Anthony and
retired to the desert.
St.
Joseph, the husband of the Blessed Virgin Mary and foster-father of
Jesus has two feasts: his official feastday on March 19, celebrated for
centuries; the second feast on May 1, celebrating the holy patriarch as a
model of workers.
