Here is another twisting and tweaking which will render new concepts and changes. It appears to me that religion is setting things up to bring in even more Pharisical iron-fisted laws. From what I have read in the past, the Noahide Laws will be the new vogue in "new system".
This word "testament" as a description of our present spiritual realm is the heritage that we have inherited from Rome, for it has come our way, due to the use of the word "testament" in the Latin Vulgate. The word gives the wrong impression of "receiving only." It contributes to the erroneous teachings of "only believe," "grace only," "good works are unnecessary," "love only." The doctrine of "only believe" is the fruit of the work of the "spirit that works in the sons of disobedience," the spirit in the Man of Lawlessness who instituted this "no-law-religion," the Great Apostasy, the Mystery of Lawlessness.
"...the "no law" religion"???
That is an understatement. Religion is made up of so many man made laws, statutes, observations, unspoken rules, and even more are made up as it goes along!
Can you see how this could be setting the stage for "love is not enough" "do more, do more, do more" and continual penance?
