Of course.
Although as I'm never going to become a member of their church and they are never going to accept me unless I do, the choice is easy.
Faith and good deeds are not always fruit in the lives of professing Christians.
I'm not sure that good deeds are "fruit" at all. You don't even have to believe in God to do good deeds, as thousands of non Christians demonstrate.
Holy Communion ought to be safeguarded.
"Safeguarded" from who?
Born again, Spirit filled Christians who eat and drink, remembering that Christ died for them are in fellowship with him. Come to that, all believers are in fellowship, or communion, with him every day - whether they take "communion" or not. God also lives in all Christians by his Spirit. There is no teaching anywhere which says that people who have the "wrong" beliefs or say the "wrong" words will lose fellowship with him, or eternal life. Nothing can snatch us from God's hands not separate us from his love. He does not "disfellowship" with us over the Eucharist.
Holy Communion must be closed because it is not merely symbolic fellowship but the real reception of Christ’s Body and Blood, requiring full communion with the Catholic Church.
That is your view, your belief and your tradition, certainly.
Jesus didn't teach that. He shared his final meal on earth with a betrayer, someone who would deny him and others who would run away when he needed them most. What belief do you think they had, at the time when they were eating the meal?
The Eucharist signifies and effects ecclesial unity; to admit those who do not profess the Catholic faith or who are in grave sin is to falsify that sign and risk sacrilege.
In your tradition, maybe.
St Paul warns, “Whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord” (1 Corinthians 11:27).
Well firstly, none of us are worthy to receive.
It is the Lord who saved us, the Lord who cleanses us, the Lord who offered his life for us and the Lord who invites us to his table.
Secondly, that verse is often taken out of context. Paul was talking about the Corinthians have divisions and not treating each other as equals. Some people arrived at the fellowship meal and found there was little left; other believers were getting drunk at the meal. They were not respecting each other. He expanded on this in the next chapter when he talks about the church being the body of Christ. Each person has a different part to play - all are important and therefore equal.
Somehow this has become, "unless you believe the same things about the body and blood of Christ as we do, you're not welcome."
The Church is not being exclusive; she is being obedient to Christ’s command and protective of the sacrament’s sanctity.
Where did Jesus say, "anyone who does not believe that this bread is literally my body, may leave this table now"?
Sorry, but your church is being exclusive.
You may believe you have good grounds for being so . If anyone were to challenge the position in a court of law, you could be let off because it is your profound belief and obviously of great importance to you. But the action, "you may receive; you may not" is not one which fosters unity.
Moreover, the Eucharist is the culmination of initiation into the Catholic faith,
You mean the
Christian faith; the Catholic church.
Christ instituted the Last Supper within the covenantal context of the Passover, which was closed to the uncircumcised (Exodus 12:48).
He wanted to share a final Passover with his friends, who all happened to be circumcised Jews.
That analogy doesn't work anyway, because I am a believing, baptised Christian.
This was not a public meal but a covenantal rite for those fully united to Him.
How far was Judas "fully united to him"?
Are you implying that non Catholics aren't?
To open Communion to those outside the Church or in a state of mortal sin is to ignore both the biblical precedent and the doctrinal integrity of the sacrament.
So Judas wasn't "in mortal sin" when he took part in the Last Supper?
I don't believe there is a "biblical precedent", Believers broke bread daily after the ascension - there is no record of what they believed and whether or not they were sinners.
Paul didn't say that some Corinthians should be excluded from the Lord's Supper.
