The Creator, the Almighty
Catholics believe that there is only one God, but that this is one God in three Persons, otherwise known as the Holy Trinity. Jesus Christ, Second Person of the Trinity, reveals the Trinitarian nature of God at various points during his ministry, as is recounted in the New Testament. There, Christ talks about a Father in heaven who loves us, and about the sending of the Holy Spirit. Christians are therefore baptised in the name of the Father, and of the Son and of the Holy Spirit.
The term “Father” signifies that God is the source of all creation. He is also called the Almighty, which reveals his omnipotence and omniscience. However, he is not a remote Creator, but a loving Father, who is involved at every stage of his creation.
God the Father therefore has a parental relationship with all his children. This is expressed by both fatherhood and motherhood, showing that he transcends the human distinction between the roles, and emphasising the intimacy between God and us, his children.
Jesus reveals that God is Father in this sense, but also that the Son and the Father have a unique relationship, which is also intimate: “No one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal Him” (Matthew 11,27). This tells us that fatherhood is eternally part of God’s nature. And this eternal relationship of Father, Son and Spirit serves as a model for the family.
Jesus also reveals that since God is Father of us, his children, and Father to his only Son, we are adopted as his children in a different sense, in that we partake in the eternal relationship of the Trinity. Thus we can cry out with Jesus in a very intimate and personal way, “Abba, Father” (cfr Romans 8,15).
