David Garland writes, “The adverb (anaxiōs, unworthily) refers to doing something that does not square with the character or nature of something (cf. Eph. 4:1; Phil. 1:27; Col. 1:10; 1 Thess. 2:12).” David Garland, 1 Corinthians: Baker Exegetical Commentary on the New Testament (Grand Rapids, MI: Baker Academic, 2003), 550.
