Hebrews 1:8-9
But of the Son he says,
“Thy throne, O God, is for ever and ever,
the righteous scepter is the scepter of thy kingdom. Thou hast loved righteousness and hated lawlessness;
therefore God, thy God, has anointed thee
with the oil of gladness beyond thy comrades.”
The reason the Church came to believe in the Trinity was because Jesus claimed to be God and showed that He wasn’t kidding by rising from the dead. Yet, while He insisted He was God, He also did puzzling things like praying to His “Father” in heaven, calling the Father God as well, and even saying “The Father is greater than I.” At length, the Church concluded that all this boiled down to the great mystery: God is one, but his oneness is the oneness of love, not of solitary isolation. There exists within God the mystery of the family, of a Father who loves the Son and of a Holy Spirit who somehow proceeds from this mysterious union of Persons, yet all the Persons are one God. Today, thank God for the revelation of Him who is God from God.
