The ideal is to bear no malice, excite no ill-will, and to love all men. The commandment which forbids us to offend our neighbor is one which a man who is striving to attain this ideal must not do less than obey. And this is the first commandment.
The ideal is perfect chastity in thought, no less than in deed; and the commandment which enjoins purity in married life, forbidding adultery, is one which every man who is striving to attain this ideal must not do less than obey. And this is the second commandment.
The ideal is to take no thought for the morrow, to live in the present, and the commandment, the fulfilment of which is the point beneath which we must not fall, is against taking oath or making promises for the future. Such is the third commandment.
The ideal—to use no violence whatsoever—shows us that we must return good for evil, endure injuries with patience, and give up the cloak to him who has taken the coat. Such is the fourth commandment.
The ideal is to love your enemies, to do good to them that despitefully use you. In order to keep the spirit of this commandment one must at least refrain from injuring one's enemies, one must speak kindly of them, and treat all one's fellow-creatures with equal consideration. Such is the fifth commandment.
All these commandments are reminders of that which we, in our striving for perfection, must and can avoid; reminders, too, that we must labor now to acquire by degrees habits of self-restraint, until such habits become second nature. But these commandments, far from exhausting the doctrine, do not by any means cover it. They are but stepping-stones on the way to perfection, and must necessarily be followed by higher and still higher ones, as men pursue the course toward perfection.
That is why a Christian doctrine would make higher demands than those embodied in the commandments, and not in the least decrease its demands, as they who judge the Christian doctrine from a social life-conception seem to think.
This is one of the mistakes of the scientists in regard to the significance of Christ's doctrine. And the substitution of the love of humanity for the love and service of God is another, and it springs from the same source.
In the Christian doctrine of loving and of serving God, and (as the natural consequence of such love and service) of loving and serving one's neighbor, there seems to the scientific mind a certain mysticism, something at once confused and arbitrary; and, believing that the doctrine of love for humanity rests on a firmer basis and is altogether more intelligible, they utterly reject the requirement of love and service of God.
The theory of a scientist is that a virtuous life, a life with a purpose, must be useful to the world at large; and in a life of this kind they discover the solution of the Christian doctrine, to which they reduce Christianity itself. Assuming their own doctrine to be identical with that of Christianity, they seek and believe that they find in the latter an affirmation of their own views.
