“The mystery of the Most Holy Trinity is the central mystery of Christian faith and life.  It is the mystery of God in himself.  It is therefore the source of all the other mysteries of faith, the light that enlightens them.  It is the most fundamental and essential teaching in the hierarchy of the truths of faith” (Catechism of the Catholic Church, 234).

We get a glimpse into this mystery in Genesis 1:26 – “God said, let us make man in our own image, in the likeness of ourselves.” These words reveal to us the nature of God.

The feast of the Holy Trinity is also known as Trinity Sunday.

This day is notable for being the only major Christian festival that celebrates a doctrine of the church rather than an event in its sacred history. It is dedicated to the Christian belief in the Trinity – Father, Son and Holy Spirit – and falls on the Sunday following Pentecost each year.

Why is this feast celebrated at this particular time?

All three Persons contributed to and shared in the work of redemption. The Father sent His Son to earth, for

The Father called us to the faith. The Son, our Savior Jesus Christ, became man and died for us. He redeemed us and made us children of God.

After Christ’s ascension, the Holy Spirit was sent down to become our Teacher, our Leader, our Guide, our Consoler.

We should note that every Sunday is devoted to the honor of the Most Holy Trinity, that every Sunday is sanctified and consecrated to the triune God.

Do we come for Sunday mass with the right mindset and attitude or just to fulfil our day of obligation?

Sunday after Sunday we should recall in a spirit of gratitude the gifts which the Blessed Trinity is bestowing upon us.

The Father created and predestined us; on the first day of the week He began the work of creation.

The Holy Spirit sanctified us, made us His temple; on Sunday the Holy Spirit descended upon the infant Church.

Sunday, therefore, is the day of the Most Holy Trinity.

“Blessed be the Holy Trinity” (Introit) “In the name of the Father and of the Son, and of the Holy Spirit” (Gospel).

The Most Adorable Trinity! “All things” good, in nature and grace, flow from and return to the Trinity; “from Him,” God the Father, our Creator; “through Him” God the Son, our Redeemer; “unto Him,” God the Holy Spirit, our Sanctifier (Epistle).

May we ever be “on the alert” to the presence of the Trinity in our souls! At Baptism we became the adopted “sons of the Father,” “co-heirs with Christ,” “temples of the Holy Spirit!”

In our offering of Holy Mass, “we will give glory to” the Trinity (Introit), and God will show “mercy to us” (Offertory, Communion). On this Feast we should also renew our baptismal vows that this “profession of our faith. . .may be of profit to our health, in body and soul”

(Post communion).
