Should a Catholic pray about the Book of Mormon?

A Catholic friend says Moroni’s invitation to read, ponder, and pray about the Book of Mormon is inappropriate because Christ gave the fullness of public revelation through the Apostles. Patrick Madrid applies that Catholic position to the Book of Mormon, while Jimmy Akin’s Catholic Answers dialogue distinguishes a seeker who has not identified God’s revelation from a Catholic who has already accepted Scripture and Apostolic Tradition. The friend also invokes Galatians 1:6–9 as a warning against a different gospel.
