Five Baptisms is written by Brian in chronological order from:

• birth in a conservative, small-town Methodist church
• to "falling away"
• to joining an ultra-conservative evangelical megachurch
• to becoming Catholic
• back to Methodist
• then Episcopal,
• then to becoming a None,
• along the way being baptized four times
• with his deconstruction being the fifth.

Five Baptisms contains many specific pop culture references of his life in the 80s and 90s, so that many Gen-Xers and older Millennials will be able to make connections to those different aspects.
