Denominationalism becomes an evil the moment it degenerates into bitter and bigoted sectarianism.

Conflicts between a dozen regiments is suicide to an army.

When a dozen denominations strive to maintain their own feeble churches in a community that requires only three or four churches, then sectarianism becomes an unspeakable nuisance.
I could cite many instances to prove the great progress that has been made in church fellowship.

For example, my early ministry was in a town in which the Society of Friends had a large meeting house, well filled by a most intelligent, orthodox and devout congregation.

But its members never entered any other house of worship.
