Those of us who can speak another language know that you can only make a pun on words if you are fluent on that language. It is unlikely that Jesus knew enough Greek to be able to do that. The Jesus of history may have had a rudimentary knowledge of Greek so as to engage in general conversation, similar to what an European American would have of Spanish, but he was certainly not fluent. So probably this is the work of Matthew, who adds to Mark’s version of the incident the mention of the church, which was one of his special themes, but not of Mark or Luke, who never use the word in their gospels (cf. Matthew 16:13-23; Mark 8:27-33; Luke 9:18-20; see also Matthew 18:5-21). But Luke uses it in Acts because that was one of his main concern in that work, namely, to narrate the development of the early church.
