SOLEMNITY OF THE MOST HOLY TRINITY (YEAR A)

Today we celebrate the Solemnity of the Most Holy Trinity, an undivided unity, and inexhaustible mystery at the heart of our Christian Faith which tells us that our God is not a solitary being out there, but rather One God in three Persons, the Father, the Son, and the Holy Spirit. This mystery reveals that the Eternal God is in himself, is a communion of a self-giving and life-generating love, a communion of Persons.

The Church fathers used the word Perichoresis to describe this communion of eternal self-giving love. The word describes the internal and mutual penetration of the Three Persons in perfect Unity and communion of love and of self-giving. Through the incarnation, this divine reality powerfully penetrates humanity (Deification), yet without an absorption of the latter which he leaves perfectly human.
