We believe in one God in three persons (The TRINITY). “God is not solitude but perfect communion.” (Pope Benedict XVI, May 22, 2005).
Christians do not worship three different Gods, but one single Being that is threefold and yet remains one. We know that God is triune from Jesus Christ: He, the Son, speaks about his Father in heaven (“I and the Father are one”, Jn 10:30). He prays to him and sends us the Holy Spirit, who is the love of the Father and the Son. That is why we are baptized “in the name of the Father and of the Son and of the Holy Spirit” (Mt 28:19).
