"Christianity needs to be fulfilled and it has been." -> Not according to the Bible.
"given God the need to renew Christianity," -> that translates to, God's plan failed, he didn't know what he was doing, despite what I showed you and what is yet to play out.
What appears to be playing out is, as the Jews were blinded in part for not accepting truth, likewise most of Christianity is blinded for the same reasons, until Jesus comes and exposes the lawlessness - untruths 2 Thes 2:10, 11 and his return and exposer 2:8.
