Claude Perera, «Burn or boast? A Text Critical Analysis of 1 Cor 13:3.», Vol. 18 (2005) 111-128
The dearth of external evidence in addition to the support of arguments from a transcriptional probability perspective eliminates the variants kauqh|= and kauqh/setai in 1 Cor 13:3. Besides having a syntactic problem, the variant kauqh/swmai is a theologically motivated scribal intervention. Historical facts, hinder the candidature of kauqh/somai and a syntagmatic approach does not favour either kauqh/somai or kauxh/swmai. In Paul boasting is ambivalent. "To boast in the Lord" is something positive. Furthermore, Petzer justifies kauxh/swmai from a structural point of view. On textual, grammatical and historical grounds kauxh/swmai cannot be a later addition.
