No, my FRiend, you would be believable at all if you could prove from the text (documents which pre-date the Roman abortion) that the Roman abortion is the "Church". It is your crazy cult which has started this unsubstantiated, self-proving, self-aggrandizing myth. The believers around here are simply calling it out.
The "once and for all" sacrifice will not and does not re-appear to anyone. Your cult again, crucifies to youselves the Son of God, and puts Him to open shame. This is the same despicable activity the Judaizers encouraged during the first century and Paul condemns it in the strongest of language. We repeat that condemnation. Shame on Rome.
The shadows were there simply to be pre-cursors, the celebration of bread and wine is simply to be a reminder. That your organization cannot read the simplest of Scriptures, "By this will we have been sanctified throught the offering of the body of Jesus Christ once for all." Heb. 10:10 is only proof that the mythical traditions of men have overtaken you.
We call you out into the light of Jesus, alone...if He permits. Come find a peace that the rotting flesh of Rome cannot offer...if He allows.
I am no FRiend of those who profane the Church.
