1 John 5:16 If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
"There is a sin, NOT "some sins" or "mutliple sins". Catholicism has to twist scripture to maintin it's beliefs.
To be honest; so does some of Protestantism.
