It is more to the honor of a Christian by faith to overcome the world, than by monastical vows to retreat from it; more for the honor of Christ to serve him in the city, than to serve him in the cell.
The purpose of a Christian education would not be merely to make men and women pious Christians: a system which aimed too rigidly at this end alone would become only obscurantist. A Christian education must primarily teach people to be able to think in Christian categories.
As you know, the Inquisition is an admirable and wholly Christian invention to make the pope and the monks more powerful and turn a whole kingdom into hypocrites.
Different people call on [God] by different names: some as Allah, some as God, and others as Krishna, Siva, and Brahman. It is like the water in a lake. Some drink it at one place and call it 'jal', others at another place and call it 'pani', and still others at a third place and call it 'water'. The Hindus call it 'jal', the Christians 'water', and the Moslems 'pani'. But it is one and the same thing.
The Church even now is the kingdom of Christ and the kingdom of heaven. Accordingly, even now His saints reign with Him, though otherwise than as they shall reign hereafter; and yet, though the tares grow in the Church along with the wheat, they do not reign with Him. For they reign with Him who do what the apostle says, 'If you are risen with Christ, mind the things which are above, where Christ sits at the right hand of God. Seek those things which are above, not the things which are on the earth'.
