While many other commentators have argued "against" any comma evidence here, most emphatically John Kaye's, "far from containing an allusion to 1 Jo. v. 7, it furnishes most decisive proof that he knew nothing of the verse". Georg Strecker comments cautiously "An initial echo of the "Comma Johanneum" occurs as early as Tertullian Adv. Pax. 25.1 (CChr 2.1195; written ca. 215). In his commentary on John 16:14 he writes that the Father, Son, and Paraclete are one ("unum"), but not one person ("unus"). However, this passage cannot be regarded as a certain attestation of the "Comma Johanneum.""
