AMEN! Scriptural, succinct and undeniable.
Judaism has no once and for all sacrifice and Roman Catholicism does not either.
Roman Catholics need to read Hebrews.
By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected for ever them that are sanctified. Whereof the Holy Ghost also is a witness to us: for after that he had said before, This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more. Now where remission of these is, there is no more offering for sin." -- Hebrews 10:9-18"Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
"No more offering for sin." Neither Jews nor Roman Catholics understand that. RCs still re-sacrifice Christ with every mass for debts they imagine are still outstanding, and presume their own good works provide a recompense for those sins, all in contradiction to the word of God and the completed work of Jesus Christ on the cross.
Amen
This is why it is so important to show them they are standing on the wrong side of the Cross. The Cross is empty. The price has been paid. It is finished.
