A.T. Robertson Commentary 1 Corinthians 1:15

"lest any man should say that ye were baptized into my name." — 1 Corinthians 1:15 (ASV)

Lest any man should say (ινα μη τις ειπη). Certainly sub-final ινα again or contemplated result as in 7:29; John 9:2. Ellicott thinks that already some in Corinth were laying emphasis on the person of the baptizer whether Peter or some one else. It is to be recalled that Jesus himself baptized no one (John 4:2) to avoid this very kind of controversy. And yet there are those today who claim Paul as a sacramentalist, an impossible claim in the light of his words here.
