Well, Chris Tomlin is. He’s the #1 Christian musician. So that’s pretty as much as you could ask for

. Check out his songs like “Transubstantiation” and “How Great is our God” on iTunes. He’s great.
NOT Catholic "When Tomlin is not recording or performing, he serves as lead worshiper at the Stone Community Church in Austin, Texas. As a leader of worship, he works hard to balance his role in the church with his celebrity, constantly checking his own motivations to be sure that he stays down-to-earth.

Many assume Chris is RC because Matt Maher, who IS Catholic, wrote or co-wrote several of Tomlin’s biggest huts.
Another three are Rachell Lampa, Rebecca St. James, and then Jaci Velasquez.
Rachael Lampa is, or rather she was, in that she left the music industry; she still is very much Catholic though. Rebecca and Jaci are not. Jaci is an Evangelical married to the lead singer of the Christian band Salvador.
Matt Maher and Audrey Assad are Catholic artists; besides their individual work, they both were guest artists on the last Jars of Clay album, The Shelter. Jars of Clay doesn’t have any Catholics, but two of the members were educated in a Jesuit-run school, so the openness and respect are there. Francesca Battistelli is a Catholic artist who won numerous Dove Awards. The video for “Beautiful, Beautiful” was filmed in a Catholic church.
I would have to double check this, but I think Kathy Troccoli is Catholic.
Yes, she is.
The late Rich Mullins was in the process of becoming Catholic, before his untimely death. He was scheduled to be received into the Church, having gone through RCIA. Just listen to “A Liturgy, a Legacy, and a Ragamuffin Band.” Many of the songs are derived from the Catholic Mass, “Creed” being one of the most popular.
Finally, there is Stephen Delopoulis and John Philippidis of the recently re-united Burlap to Cashmere; they are Greek Orthodox, and therefore share many of the same beliefs.
Also, Ed Kowalczyk, lead singer of the multi-platinum band Live, is a Catholic revert. He has a new album out, and the new single from it is called “Grace”.
