Yeah, there's no good reason for debate on the matter. I'll continue to attend Mass with my wife and participate in those elements of it that agree with my Protestant ideas.I pray that all of us could avoid committing a grave or mortal sin within 24 hours of the Sacrament of Penance and Reconciliation (which is often offered on Saturday). Not every sin or passing thought jeopardizes one's state of grace. Yet,
Can. 916 A person who is conscious of grave sin is not to celebrate Mass or receive the body of the Lord without previous sacramental confession unless there is a grave reason and there is no opportunity to confess; in this case the person is to remember the obligation to make an act of perfect contrition which includes the resolution of confessing as soon as possible.
And,
Grave matter is specified by the Ten Commandments, corresponding to the answer of Jesus to the rich young man: “Do not murder, do not commit adultery, do not steal, do not bear false witness, do not defraud, honor your father and your mother.” The gravity of sins is more or less great: murder is graver than theft. One must also take into account who is wronged: violence against parents is in itself graver than violence against a stranger (CCC 1858).
Whether you are fit or unfit to receive the Eucharist is a matter that would be very well known to you. It is true that few could approach the altar spotless. Reflect hard on all of your sins before doing so, and to make an act of contrition for all your sins. If there is any doubt in your mind that willful disobedience of a grave matter weighs on your soul, then why not confess those sins?
The opportunity to free yourself from these shackles is a gift of immense and immeasurable love from our Lord.
Even so, a Protestant should not take Communion at a Catholic church (and vice-versa).
But I have to admit, the exclusionary, authoritative nature of it is something that I'm not used to.
On the other hand, I can't relate at all to the current trend of contemporary Protestant services. I'm an old school, traditional Protestant--quiet, respectful services,..no jumping around and shouting stuff. My minister is very sincere and conducts the Holy Communion service in a very respectful manner.
My opinion--attending services is important. But a persons's salvation is worked out in a personal, one on one relationship between the person and God.
The Church can provide guidance, but it can't do it for you.
Again, that's just my personal, Protestant view. I don't expect Catholics or the Orthodox to see it the way I do.
