The above quotation was taken from a blog post about origins. But you could substitute a lot of things for "this," such as speaking in tongues, use of alcohol, women in the ministry, eternal security, church government, the Trinity, and interpretation of end-times prophecy. The author goes on to speak about a case where Paul, himself, didn't really answer a question -- an important question -- for the Corinthian church, and takes that as justification for not always knowing all the answers, or even expecting to. I agree.
Thanks for reading. Read the original post.
