使徒行传第十五章说保罗和巴拿巴在外邦传福音，有几个人从犹太下来，教导弟兄们说：“你们若不按摩西的规条受割礼，不能得救”。保罗和巴拿巴就与他们大大的分争辩论，但从犹太下来的这几个人不服，就派保罗，巴拿巴和几个人就这件事去耶路撒冷咨询其他的使徒与长老。保罗他们到了耶路撒冷，那里有几个信徒是法利赛教门的人，也起来说：“必须给外邦人行割礼，吩咐他们遵守摩西的律法”。可见，这些法利赛人虽然是信徒，但是他们依然处于吃奶的基督徒阶段，他们还没有按耶稣所说的否定他们的旧人去靠耶稣得救。因此，他们仍然把行割礼作为得救的前提。这不禁让人想起，在马太福音里耶稣曾说过，凡文士受教作天国的门徒，就像一个家主的库里既有新的东西，也有旧的东西，他会同时拿出它们来。因此，他们的教导对信福音的外邦人来说是一种迷惑，后来保罗在他的书信里多次警告弟兄们要小心这些教导。另外，注意这里的经文用的是“几个人从犹太下来”，而不是“几个门徒从犹太下来”。
