The answer
Definitely, for what has been taught about the Trinity was revealed by God Himself to us in His Holy Scripture. This was first alluded to in the Old Testament, and then explicitly indicated in the New Testament. Here are a few examples:
“Go therefore and make disciples of all the nations, baptizing them in the Name of the Father, and of the Son, and of the Holy Spirit” (Matt. 28:19).
The Father, the Son, and the Holy Spirit are Three Hypostases in One God, which is why He did not say “names,” but rather said “Name,” because God is one.
St. John the Beloved says, “For there are Three that bear record in heaven, the Father, the Word, and the Holy Spirit: and these Three are one” (1 John 5:7).
In the event of the Baptism, we see the One God being revealed in His Three Hypostases: the Voice of the Father from Heaven, the Incarnate Son immersed in the River Jordan, and the Holy Spirit in the form of a dove settling on the head of the Word Incarnate (Matt. 3:13-17).
