Meaning of Holy Trinity

What is Holy Trinity:

The Holy Trinity is the fundamental dogma of Christianity. It consists of the belief that God is one and triune, that is, it is a unit made up of three divine persons related to each other: the Father, the Son and the Holy Spirit. This principle of communion of three persons in one God is also known as hypostasis.

The catechism of the Catholic Church defines it as follows:

According to the different confessions of Christianity, the Holy Trinity has been manifested throughout the Old Testament and the New Testament. But the full revelation of the mystery of the Holy Trinity is attributed to Jesus himself, both judging by his manifest relationship with God, whom he called "Father", and through his testimony and his teachings.

Within the framework of dogma, God the Father is the creator of life in all its forms and manifestations. Jesus is the only Son of God, who proceeds from his own nature and accepts to incarnate himself in Humanity to fulfill the Father's designs. Finally, the Holy Spirit, who comes from both, is the one who infuses life and inspires actions and words of good in hearts.

Biblical foundations

The belief in the Holy Trinity rests on the interpretation or exegesis of various books of the Bible. The following examples serve to illustrate this point:

In the book of Genesis, the narrator puts God's voice in the first person plural on more than one occasion. For example: "Let us make man in our image, according to our likeness ..." (Gn 1:26).

Throughout the Gospels, these interpretations take on more shape, thanks to the words of Jesus. For example: "Philip said to him:" Lord, show us the Father, and that is enough for us. " Jesus replied: «I have been with you for so long, and you still do not know me, Philip? Whoever sees me sees the Father. How is it that you say: Show us the Father? " (Jn 14, 8-9).

Another example that we can record is in the Gospel of Matthew: “Go, then, and make all the peoples my disciples. Baptize them in the Name of the Father and of the Son and of the Holy Spirit ”(Mt 18:19).

The Evangelist Saint John reflected abundantly on this matter, laying the foundations of Trinitarian theology. This is visible in the first chapter of his gospel: “No one has ever seen God, but God the only Son made him known to us; he is in the bosom of the Father and made him known to us. " (Jn 1, 18). The same was also done by the Apostle Paul in the pastoral letters he addressed to his communities: "For in him all the fullness of the Godhead dwells bodily" (Col. 2, 9).


The dogma of the Holy Trinity is a concept that claims to define the nature of the God of Christians. This concern was not formulated in this way before the Romanization of the Church, because in times of persecution, Christians concentrated on reflecting on the mission of Jesus.

The issue became a central debate after the institutionalization of the Church. Thus, the Council of Nicaea (year 325), promoted by Constantine, head of the Byzantine empire, took care to define the nature of the Son with respect to the Father. Then the Council of Constantinople (AD 381) recognized the Holy Spirit and, finally, the Council of Chalcedon (AD 451) ratified it. Thus, the doctrinal prayer of the Church par excellence was given definitive shape: the creed.

However, the issue was not therefore a finished debate. The inquiries of Saint Augustine of Hippo or Saint Thomas Aquinas on this dogma are famous. However, Christianity continues to be based on the formulation born of the first councils.
