Please, ANYone can walk into a Mass, sit and "be there." The doors are ALWAYS open to ALL. The priest CAN'T refuse someone because he THINKS that a person may be in the state of sin. What those sinners do is between them and God and not your business to judge.
You know that and are just lecturing me for your own benefit.
I think you missed the point of Petrosius' post. He is explaining the true meaning of the Mass, not lecturing you. Mass is the wedding feast of the Lamb, being there is EVERYTHING, whether one partakes of Communion or not. Even the excommunicated are still required to attend each Sunday and holy days of obligation.
I am a convert, and the church where I joined messed up my confirmation process (may have been a very liberal priest, I don't know exactly how this happened) by confirming me and giving me Communion but not first con-validating my marriage to my cradle Catholic husband. Low and behold, four years later my new parish figured out what happened and let me know I had been receiving illicitly all that time! So now I have to wait while hubby and I go through the process before I can take Communion again. Could take 6 months. But I am still required, and am going, and tremendously ENJOYING the Mass, because He is still there, and I can still be a part of that miraculous sacrifice each week. Sometimes twice if I sit in with my kids' all-school Mass on Fridays. :)
Mass, for me anyway, is as much about GIVING as it is about RECEIVING.
And as for the article, whatever crap comes down the pike, Christ in the Eucharist brought me to the Catholic Church and that is who will keep me there. :)
