Alpha, the first letter of the Greek alphabet, as Omega is the last. These letters occur in the text of Revelation 1:8 Revelation 1:11 ; 21:6 ; 22:13 , and are represented by "Alpha" and "Omega" respectively (omitted in RSV, 1:11 ). They mean "the first and last." (Compare Hebrews 12:2 ; Isaiah 41:4 ; 44:6 ; Revelation 1:11 Revelation 1:17 ; 2:8 .) 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.
