It’s not Biblical interpretation, it’s Biblical teaching. I am not saying, “hey the Olive tree represents this or that”. I am just paraphrasing what the Apostles wrote in plain language, which is unmistakeable. Even Christ himself said “It is finished” with his last breath.
If you don’t feel Christ’s death on the cross was a perfect enough payment to cover the wages of sin, for anyone, for all time, then I feel sorry for you and I hope God opens your eyes.
We can go on forever about the interpretation of Christ’s death. It sure opened the door to salvation to all of us but that doesn’t mean we get a free pass. This brings us back to the initial proposition, namely the authentic teachings of Christ as reflected not only in scripture, but in all what was handed down to the Apostles and their successors including those acts that were recorded and those that were not, what Christ said that was written and what was not written. Scripture alone won’t cut it. This is why in establishing His Church on earth He entrusted to Peter the keys to the Kingdom of Heaven. “Whatsoever thou shall bind on earth will be bound in heaven and whatsoever thou shall loosen on earth, shall be loosened in Heaven.”
And again we revert to the threshold question. Whose interpretation of Scripture, revelation, and tradition do we accept? You have on one hand the Catholic Church and on the other hand some 35, 000 other Christian denominations including the likes of Joel Osteen; “Bishop” TD Jake; Rev. Sharpton; Rev. Wright; David Koresh; Rev. Jim Jones; or gay and lesbian ordinations of Christian bishops like Lutherans, Episcopalians, and Anglicans or simply trust you own interpretation and judgment like what the Gnostics tried to do? To ask this question is to answer it.
