Luke 3:22
Luke 3:22 reads as follows:
Luke 3:22 (ESV): and the Holy Spirit descended on him in bodily form, like a dove; and a voice came from heaven, “You are my beloved Son; with you I am well pleased.”
Instead of "You are my beloved Son; with you I am well pleased," one Greek manuscript, Codex Bezae, has the variant reading, "You are my Son, today I have begotten you." Some have argued that because several Church Fathers (i.e. Justin Martyr, Clement of Alexandria, Methodius of Olympus, Hilary, and Augustine) witnessed to this variant, that is must be taken as the original wording.
However, the weight of the manuscript testimony is against this variant reading (see NET Bible Commentary on Luke 3:22). There are literally hundreds of Greek manuscripts of Luke and all but this one manuscript (i.e. Codex Bezae) have the majority reading.
The following quotes are from the Reddit post: Which reading of Luke 3:22 is more probably the authentic one?.
The only Greek witness to the variant is Codex Bezae. Some may be inclined to prefer it, but this is generally on theological grounds rather than textual. Ehrman's argument is based primarily on the grounds of his belief that the earliest Christians were adoptionists, and therefore the reading that is most adoptionist-like must be more original. However, Bezae is known to contain many unique readings throughout, and scholars have argued that these changes seem to have been made for theological reasons. As this article, Luke 3:22-38 in Codex Bezae, states: "E. J. Epp's work, The Theological Tendency of Codex Bexae Cantabrigiensis in Acts, has shown the existence of definite biases lying behind the variant readings in Acts.' A similar study of Luke indicates that theological biases promoted variant readings in this book as well. (George E. Rice, The Alteration of Luke's Tradition by the Textual Variants in Codex Bezae (Ph. D. dissertation, Case Western Reserve University, 1974))"
Although we do not have the extant autograph of the Gospel of Luke, and so cannot say for 100% certainty that the majority reading is original, the critical study of the manuscript witnesses demonstrates that it is certainly most likely.
