How about getting him a special limited edition vinyl record of his favorite gospel artist or album? You could also consider getting him a deluxe box set of gospel songs or an autographed copy of a biography of his favorite gospel artist. Alternatively, if he likes to sing, you could gift him a karaoke machine that has gospel songs in its library as a gift. If he is a fan of live performances, you could also look for upcoming gospel concerts and purchase tickets for both of you to attend.
Or you can get him a star map with the date of your anniversary.
