Alpha and Omega

Scholar Robert Young stated, with regard to "I am the Alpha and the Omega" in 1:11, the "oldest [manuscripts] omit" it.

Alpha (Α) and omega (Ω) are the first and last letters, respectively, of the classical (Ionic) Greek alphabet.

"[7] Most Christian denominations also teach that the title applies to God (Jesus, the Father and the Holy Spirit).

In fact, despite always being in Greek, the letters became more common in Western than Eastern Orthodox Christian art.

Some dialects of the APL programming language support the direct function syntax where the left (optional) and right arguments are denoted by the letters alpha and omega.
