Nicolas in Fausset's Bible Dictionary
Of the seven. Probably having no connection with the
Nicolaitans, though Epiphanius (adv. Haer. i. 2, section 25)
represents him as sinking into corrupt doctrine and practice.
Clemens Alex. (Strom. iii. 4) says that Nicolas, when
reproached by the apostles with jealousy, offered his wife to
any to marry, but that Nicolas lived a pure life and used to
quote Matthias' saying, "we ought to abuse (i.e. mortify) the
flesh." No church honours Nicolas, but neither do they honor
four others of the seven men. Confounders of Nicolas with the
Nicolaitans probably originated these legends.
