What does the phrase "ability to redeem its rival religions of the book" mean here?
"[In] 2 October 1586 ... the Welsh minister Meredith Hanmer preached a sermon at St Katharine’s Church next to the Tower of London, entitled The Baptizing of a Turke [Shinano]. This was the first recorded example of a Muslim converting to English Protestantism....While it [the sermon] used Chinano’s conversion as a sign of Protestantism’s growing ability to redeem its rival religions of the book, it left other concerns about religious conversion unanswered. How genuine was Chinano’s baptism, and what could prevent him from reverting?"

It's actually "...the Book...." and they are referring to the Bible.
Any religion that does not ascribe to the Bible is "rival religion" Chinano followed Islam and Islam is a rival religion to Christianity.
