Not anymore, but there’s some confusion about it.

From Damien Thompson:

I came across this curious article from Politics Daily which (without apparently realising that it is doing so) reveals that he has abandoned the faith of his Cuban parents:

What is Marco Rubio’s religion?

Rubio is a Roman Catholic.

Where does Marco Rubio worship?

Though he is Catholic, Rubio belongs to the Christ Fellowship nondenominational Church in West Kendall, Fla., where he has attended for the last six years.

Was Marco Rubio born Roman Catholic, or did he convert?

Rubio was born Roman Catholic.

What has Marco Rubio said about the Roman Catholic Church?

When asked about how his faith has sustained him, Rubio said that he derives his family’s strength from faith. “If you get the personal part of your life wrong, nothing else makes sense,” he said, adding that his most important job is father and husband, and “I try to get that right, … and certainly that comes from our faith.” As a Catholic potential senator, he has expressed a possible division (as well as an inference that his Christianity informs his morality): “For those who have the Christian faith and are in politics, there is a constant struggle between a desire to do what is right and how that sometimes may not coincide with what is popular,” he said. “I hope that, more often than not, I make the right choice.”

There’s more at the link about the church where Rubio worships, and Thompson has followed up on the issue here.
