How We Experience God’s Love: The Mystery of God

The Mystery of God

Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.
Matthew 28:19

The Trinity is Mystery

Christians could never have discovered for themselves that the God they worship is one God in three Persons. They know this central dogma of Christian faith and life only because Jesus revealed it to the Apostles during his life on earth and because he sent the Spirit to confirm it after Jesus himself ascended to the Father. Even now, humans cannot imagine what the inner life of the Trinity is really like. It is a mystery "infinitely beyond all that we can humanly understand." (See the Catechism of the Catholic Church, 251).

The Communion of Love

The love among Father, Son, and Holy Spirit—so intense that the human mind cannot conceive it—is nevertheless the very love which you, by virtue of your Baptism, are invited to share. Throughout the process of creation and redemption, God's ultimate goal has been that all humans would enjoy living in unity and love as in the communion of the Trinity. The communion of love that exists among the three Persons of the Trinity is the pattern on which God intends you to model your relationships with others. Although you may enjoy a foretaste of this communion here on earth, it will be fully realized only in the fullness of the Kingdom of God.

Jesus commanded his followers to love one another because only by loving could they be united with a God who is love.


  • When did you first come to "know" about God?
  • Which of the Three Persons of the Trinity do you most communicate with?
  • How are you an example of the communion of love?


Most Holy Trinity, Open me to the power of your love. Amen.
