The Holy Trinity -
The Trinity is one of the greatest mysteries of the Catholic faith. Catholics believe that there is One God. Yet, the One God has three persons who are equally God. God the Father, God the Son and God the Holy Spirit are the three persons of GOD and are all of the same nature, substance and being. I have heard it explained that if the Trinity was to be explained by math, it would not be, 1+1+1=3. It would be 1x1x1=1.
The Father is unique from the son because the Father has no origin. He is self-existing or eternal. But, Jesus, the Son, is eternally begotten, from the Father or proceeding from the Father. Jesus is God’s word made flesh. Lastly, the Holy Spirit eternally proceeds from both the Father and the Son. He is God’s love and does God’s work.
Interestingly enough, the word “Trinity” is a term that is not found in the Bible. Nevertheless, the Bible clearly speaks of God the Father, God the Son (Jesus Christ), and God the Holy Spirit; and also clearly states that there is only one God.
The Gospel of John 16: 13 – 15 is a good example of scripture referring to the Trinity. “But when he comes, the Spirit of truth, he will guide you to all truth. He will not speak on his own, but he will speak what he hears, and will declare to you the things that are coming. He will glorify me, because he will take from me what is mine and declare it to you. Everything the Father has is mine; for this reason I told you that he will take from what is mine and declare it to you.”
