Seriously I’d tell them, “Hello, how are you today?”
If you’re talking about what I’d like to say to them in terms their faith or the like I’d really have nothing to say as I don’t have any issue with them being Catholic (provided they’re active in their faith). Catholicism to me is just another slightly different branch of the same Christian tree I’m on. There are of course some differences in theology and sociology but I’ve never felt the differences are enough that Catholics are in some danger of their souls or anything like that. They don’t need to go anywhere IMO if they don’t feel the need.
Now if they were inactive Catholics are “lapsed Catholics” I might ask them why they’re not active and frame a conversation and questioning from there.
Here my Friend are 2 highly significant differences:
[1] The REAL Presence of Jesus Christ in every Catholic Church of the world
Mt 26:26-28
MK 14: 22-24
Lk. 22: 17-20
John 6: 47-57
Paul 1st Cor. 11:23-30
AND SUPPORTED by the Early Church’s acceptance and pratice
Luke 24:35
And they told what things were done in the way; and how they knew him in the breaking of the bread.
Acts Of Apostles 2:42
And they were persevering in the doctrine of the apostles, and in the communication of the breaking of bread, and in prayers
[2] Forgiveness of our sins GOD"S WAY [or it wouldn’t be in the Bible]
1John.1 Verses 8 to 10 If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us."
1John.5 Verses 16 to 17 "If any one sees his brother committing what is not a mortal sin, he will ask, and God will give him life for those whose sin is not mortal. There is sin which is mortal; I do not say that one is to pray for that. All wrongdoing is sin, but there is sin which is not mortal.
John.20 Verses 20 to 23"On the evening of that day, the first day of the week, the doors being shut where the disciples were, for fear of the Jews, Jesus came and stood among them and said to them, “Peace be with you.” When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. Jesus said to them again, “Peace be with you.** As the Father has sent me, even so I send you.**” And when he had said this, he breathed on them, and said to them, “Receive the Holy Spirit.
If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.”
These Sacraments require direct Apostolic Succession; not found out side of the Catholic & Orthodox churches.
