No, but we are condemned by God for preaching a perverted gospel (Galatians 1:9). The only unpardonable sin is to deny the Holy Ghost, which is an indication that an individual is not saved (Matthew 12:31).
“Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming.”
-Ephesians 4:14
