I agree that the division among Christians into various sects creates enormous difficulty for many people in many situations. The unity of all Christians will be a fantastic thing and it will, I believe, give due recognition to the Bishop of Rome as the successor of Peter.
I remain unconvinced that there is a lot I could say to my neighbor who is a Methodist or a Baptist or whatever - that would speed the attainment of that unity. There is much I can do. Every day I can live as close to the example of Christ as possible. I can practice my faith and I can pray for unity. I can do those things I strongly believe those things are worth doing.
However, I don’t think discussions about why they should “convert” to Catholicism will be fruitful unless, by some circumstance, they are really open to that possibility. (Perhaps a falling out with their own parish or some other crises. Even then, I think I could offer them “a share in my faith community” with all the advantages that would provide, but I don’t think it would be as helpful to offer them "a chance to finally do things right.)
Divisions among Denominations occured when people in powerful leadership postions did stupid things. I think those divisions will only heal when people in such positions are ready to do the right thing. If I am in such a position, then I would be culpable to at least some extent if I failed to speak up. To the extent that I am simply someone’s neighbor, I believe that what I do will count for much more than what I say.
Thanks for clarifying your position.
peace
