A plethora of what-if questions. We could daily play that game until the end decade with room to spare.So believing in demonic doctrines isn't so bad?
I guess you would have to backpedal on that, once you realize the implications for your own doctrine relative to mine.
Was selling Joseph into slavery evil? God planned that (Genesis 50:20).
Was crucifying Jesus evil? God planned that (Acts 4:27-28).
When the Israelite priests burned the sacrifices brought to them, were they intended to cover the sins of everybody, or just the persons who brought their offering?
On the Day of Atonement, did the high priest make atonement for the Philistines and Amalekites, or just the Israelites?
Jesus is our high priest. Does he make intercession for his own people, the church, or for everyone, inside the faith or out? Did he present himself as an atoning sacrifice for all the pagans only for the Father to tell him it wasn't acceptable?
Put another way: does your church warn unbelievers to pass the Communion elements by? Why? If Christ's body was broken and his blood shed for them just as it was for the church, then every person, faithful or not, partakes in the New Covenant, no?
Put yet another way, every priest intercedes for some men, not all men.
To answer your ending question, my church request that only believers participate in communion, whether church member or visitor.
This isn’t complicated: when the Bible uses the word all, it means every person, otherwise it would use the word some.
