Parking of the eucharist/communion is an outward sign of being properly prepared as well as unity with the church that you are taking it at. If you are not Catholic then you are not prepared or in unity with the church, why would you want to pretend otherwise?
As far as I am concerned I would not be pretending anything.
There is one God, one Saviour, One Holy Spirit and one Gospel. All who receive Christ have eternal life, John 6:40, are children of God, John 1:12 and have passed from death to life. That's everyone - Catholics, Anglicans, Baptists, Methodists, non denominational or someone in deepest Africa who has just been taught the Gospel.
I don't agree with some aspects of Catholic teaching but I have often said on these forums that they are my brothers and sisters in Christ. We have the same Saviour and same heavenly Father - of course we are in unity. The Catholic church might not see it that way but that is what I believe Scripture teaches.
When I was in a Catholic church,
at their invitation, it would have been nice to have received communion, with them, as fellow Christians together.
Yes, maybe in their eyes I'm the same as an infidel/not worthy of it/out of communion with the church. I don't see it that way and, fwiw, I don't believe God does either.
Though it is academic in a way as I doubt I will ever go to a Catholic church again.
I am in an impaired state with the RCC and can't take communion either.
According to the Catholic church, maybe not.
I'm sure you'd be very welcome to receive it elsewhere.
The Eucharist matters to the Catholic Church,
It matters to me too.
It matters very much that Jesus told his disciples to "do this in memory of me" and churches, of all denominations, impose man made rules which exclude people.
it isn't just a symbol and it isn't just sharing a meal - it is the literal body and blood of Christ,
When we have communion the Minister says "the body of Christ to keep you in eternal life" - that is what it is and that is what we receive.
I'm not going to get into an argument about whether it remains a piece of homemade/shop-bought bread or turns into literal flesh; I don't see that that's necessary and Scripture doesn't teach it.
If Catholics remain adamant that I am not receiving the body of Christ or regard it appropriately; so be it.
They would have no right to judge nor to comment on my relationship with the Lord. Especially not on a public forum in a thread which claims to be interested in unity.
