Just Info sharing in hopes that it helps someone else as it took me forever to find a decent template for a catholic ceremony. This is the best I found and easy to edit: https://thebudgetsavvybride.com/free-catholic-wedding-program-template/ and incorporated these guidelines: http://catholicweddinghelp.com/topics/catholic-wedding-program-template-mass.htm
I know many forgo the programs anymore but wanted to pass along as it helped me out a great deal!
