A Alpha, the first letter of the Greek alphabet, as Omega is the last. These letters occur in the text of Revelation 1:8, Revelation 1:1; Revelation 1:21; Revelation 1:22, and are represented by "Alpha" and "Omega" respectively (omitted in R.V., 1:11). They mean "the first and last." (Comp. Hebrews 12:2; Isaiah 41:4; Isaiah 1:44; Revelation 1:11, Revelation 1:1; Revelation 1:2.) In the symbols of the early Christian Church these two letters are frequently combined with the cross or with Christ's monogram to denote his divinity.
