My answer is no. Faith in Christ...knowing that He is the only way and that he finished it is truly what faith is. What if I came to this site and professed that I believed in Christ, but I also practiced witchcraft.... Or that I believed in reincarnation as a way of being reborn but still believing in Christ? It doesn't work. We can not serve both sides. We can not serve paganisim and Christianity. The same thing for believing in purgatory..."yes I believe in Christ...but I believe he only did half a job...I need to burn off the rest of my sin...yada yada..."
