A co-worker of mine said that Protestantism is justified as Christianity because times are changing. We are “progressing into the time of Revelation” and as we progress so does the truth. “Christianity is a religion of progression.” I couldn’t find much to say in response. He also stated that just Jesus Christ came to fulfill Judaism and since the Jews were so corrupt, Christianity began. Christianity is an extension and continuation of Judaism the way Protestantism is to Catholicism.
What can I say to these claims and can anyone show me good information to better understand what he’s talking about?
