This is how I see it.
At various points in the past, men split God’s house.
As time went on, these splits became permanant, or at least long lasting.
God, being a merciful God, decided that to allow these sheep no shepherd when it is not their fault that they are wandering would make it hard for them to come home.
God, in His mercy and wisdom, calls men to lead them as best they can, with the limits on the Truth that Man imposed on these fractured denominations.
Yes, God calls them, but not because they are right in their choice of denomination. It is because God wills the salvation of all men.
