Great topic!

But the visible church is in a sense already catholic.

WCF 25:2 The visible church, which is also catholic or universal under the gospel (not confined to one nation as before under the law), consists of all those throughout the world that profess the true religion; and their children: and is the kingdom of the Lord Jesus Christ, the house and family of God, out of which their is no ordinary possibility of salvation.

And I do believe the unity of the Catholic church will be restored. This is why the national establishment of the church is so important! Christians should be more careful not to rupture the body of Christ. Some have advocated that we should not separate from a church unless something sinful is required as a term of communion with her. Under what conditions do you think christians can legitimately separate from a church?

"The greatest thing we can desire, next to the glory of God, is our own salvation; and the sweetest thing we can desire is the assurance of our salvation. In this life we cannot get higher than to be assured of that which in the next life is to be enjoyed. All saints shall enjoy a heaven when they leave this earth; some saints enjoy a heaven while they are here on earth." Joseph Caryl
