QUESTION: What kind of sin is it if one curses Jesus as Satan? Is it an unforgivable sin?
ANSWER: Sin is only unforgiveable if we are unrepentant when we die. The condemnation of the divine as satanic is a serious sin: “The scribes who had come from Jerusalem said, ‘He is possessed by Beelzebul,’ and ‘By the prince of demons he drives out demons.’ Summoning them, he began to speak to them in parables, ‘How can Satan drive out Satan? If a kingdom is divided against itself, that kingdom cannot stand. And if a house is divided against itself, that house will not be able to stand. And if Satan has risen up against himself and is divided, he cannot stand; that is the end of him. But no one can enter a strong man’s house to plunder his property unless he first ties up the strong man. Then he can plunder his house. Amen, I say to you, all sins and all blasphemies that people utter will be forgiven them. But whoever blasphemes against the holy Spirit will never have forgiveness, but is guilty of an everlasting sin.’ For they had said, ‘He has an unclean spirit’” (Mark 3:22-30).
