Gospel according to Jesus wrote: When the man approached Jesus asking "What must I do to be saved?" what did Jesus say?
Jesus replied; 'Keep the Commandments.' Matt 19:18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
Roman Catholics are "false witnesses."
For example they worship graven images, which is disobeying God's Commandment.
