It depends on what you mean by "set aside."
Do I think Catholics and Protestants will ever reunite and become one Church, one Faith, etc? No. In order for the Christian Church to reunite and become one in Faith, Protestants would---have to give up--everything that makes them Protestant. I do not see that happening. The differences between Catholics and Protestants are not like the differences between say--Weis Markets and Tops, Pizza Hut and Dominos, Burger King and McDonalds. One may suggest that the differences between the Protestants sects are more analogous to that, but not the differences between Protestants and Catholics.
Catholicism is different in essence from Protestantism. The differences between Catholics and Protestants is not degree but kind. The differences between Protestants are degree, not kind. Thus, reunion--I do not see happening.
That being said: I disagree with Protestants, but I have always respected them as brothers and sisters in Christ. I have always thought them well intentioned people who I disagree with. You do not see me in their churches attempting to prostitlilize them. You do not see me attempting that with family or friends. I would not encourage Catholic converts to run around badmouthing the sect they left--to anyone who will listen--especially current members of that sect. When I was organist in a Five Point Calvinist church, the pastor asked me if I had a problem with Five Point Calvinism. I said "Hell yes I have a problem with that. If I agreed with it, I would be a member of your Church! But as organist, I am a guest in your house. Your house, your rules. I am just here to play the organ." The pastor hired me on the spot.
I wish Protestants could just accept that we disagree and leave it at that. So we have devotion to Mary, we believe in Purgatory, we have devotion to the saints, etc. So what? So we have Sacraments. Why are Protestants so obsessed with this? Why are they so hung up on this. It is as if they think we Catholics literally walk around all day going "Jesus, who cares about you, I want to talk to your mother." I just do not understand why they care. Obviously you are Protestant becasue you do not believe these things. Fine. Whatever. Do what you want in your sect. Leave us to our practices and Faith.
