If Christianity became corrupt soon after the death of all the apostles, then why do Mormons accept the New Testament as Scripture since it wasn't affirmed as such until the fourth century or so? Also, do Mormons use the Protestant Bible rather than the Catholic one (the difference I am referring to being not the translation, but the books included in the Old Testament)? If so, then why accept Martin Luther's changes to the Bible which were made long after you believe Christianity became corrupt? Those books were affirmed as Scripture and included in the Bible at the same time as the books in the New Testament, so why reject the seven OT books but not the NT ones?
