As an adult, from 2000 to 2004 Rubio took a detour from his Catholic roots to exclusively attend Miami's Christ Fellowship, a Southern Baptist megachurch to which Rubio has given at least $50,000.
Now straddling both Christ Fellowship and the Catholic Church, Marco Rubio seems positioned to appeal both to conservative Catholics but also the anti-LGBT, demon-casting, creationist segment of the Protestant evangelical right.
Though he's now primarily and "firmly" Catholic, Rubio has recently told Religion News Service reporter Sarah Pulliam-Bailey that he has "maintained the relationship with Christ Fellowship" and often attends services at the church.
