Note 2 at Mk. 1:10: All three persons of the Godhead are in manifestation at once: (1) the voice of the Father, (2) the Son in His physical body, and (3) the Holy Spirit in the shape of a dove. This shows that the three persons of the Trinity are distinct from each other, and yet, scripture reveals that They are one (1 Jn. 5:7). The Greek word for "one" in 1 John 5:7 is "heis" and signifies a single one to the exclusion of others, as well as united in purpose. This same Greek word is used in 1 Timothy 2:5, in which case it clearly means more than sameness of purpose.

The Trinity is first suggested in Genesis 1:26 by God saying, "Let us . . . ." One God spoke in the plural. Scripture has abundant references to the Father as God (Exa. 1 Cor. 8:6). Jesus is called God (Isa. 9:6; Jn. 1:1; 20:28; 1 Tim 3:16; Heb. 1:8). The Holy Ghost is called God (Acts 5:3-4). Yet one of the great statements of the Old Testament from Deuteronomy 6:4 says that, "The Lord our God is one Lord." We do not have three Gods, but one God, clearly identifiable as three persons. This is a great mystery, which we do not have any adequate explanation for. Scriptures reveal the truth of the Trinity but make no attempt to explain it. We simply accept this revelation as it is, until we know all things, even as we are known (1 Cor. 13:12).
