The measure of the Church

In this wicked world, in these evils, when the Church measures her future loftiness by her present humility . . . when she soberly rejoices, rejoicing only in hope, there are many reprobate mingled with the good, and both are gathered together by the gospel as in a drag net . . . until it is brought ashore, when the wicked must be separated from the good, that in the good, as in His temple, God may be all in all. (Augustine City of God p660)

It is, in my opinion, important that children learn early that the gospel gathers both the good and the bad, and that in this age the Church is a mingled multitude, measuring her future loftiness by her present humility (not iniquity!). Then we will learn how to love one another within the Church through the gospel, confident that it is the power of God to save those who believe - and to convert those who are in the Church and have not yet truly believed. We do this that God may be all in all to all.
