That has been experience also when talking to Mormons, Jehovah's Witnesses, Christian Scientist, etc.
When the Scriptures disagree with their theology, they pull out the "Scriptures are corrupt in that particular verse" game.
Even most Protestants play a similar game by rejecting some of the 73 books of the Bible accepted by Catholic and Orthodox Christians.
Singling out the Muslims for playing the cafeteria game with the Bible is not very convincing.
The Catholic Church, therefore, recognizes that Protestants, Jews, and Muslims worship the same God as Catholic and Orthodox Christians.
I agree with the Catholic Church Catechism.
I don't think this is in the same league. Prior to "canonization" of New Testament scriptures by either Protestants or Catholics, some of the books studied were thought to be good but not at the same level of inspiration as the apostolic works.
Protestants merely canonized the works that were clearly apostolic in origin. That the Catholics later canonized the apocrapha, including some books that were not apostolic or whose origins were in doubt, should not be construed as Protestants picking and choosing to suit themselves.
