I was raised Protestant but my wife and kids are Catholic and we attend Mass each week. I have not yet made the decision to convert as I am still hung up on some of the differences between the Catholic Church and how I was raised. But I do enjoy attending Mass and participating to the fullest extent that I can.
What am I as a non-Catholic permitted to do in the Mass and what am I not permitted to do? Are there some things that I am permitted to do but it is not recommended that I do? I certainly know that I cannot take Communion, but what about the other activities and postures? I routinely do go forward during Communion to receive a blessing along with my younger boys. Is this okay? Also, is it appropriate for me to genuflect; make the sign of the cross; raise my hands during the Lord’s Prayer; cross my forehead, mouth and heart when the Gospel is read; etc.?
