The animal existence of a man does not constitute human life alone. Life, according to the will of God only, is also not human life. Human life is a combination of the animal life and the divine life. And the more this combination approaches to the divine life, the more life there is in it.
Life, according to the Christian religion, is a progress toward the divine perfection. No one condition, according to this doctrine, can be higher or lower than another. Every condition, according to this doctrine, is only a particular stage, of no consequence in itself, on the way toward unattainable perfection, and therefore in itself it does not imply a greater or lesser degree of life. Increase of life, according to this, consists in nothing but the quickening of the progress toward perfection. And therefore the progress toward perfection of the publican Zaccheus, of the woman that was a sinner, and of the robber on the cross, implies a higher degree of life than the stagnant righteousness of the Pharisee. And therefore for this religion there cannot be rules which it is obligatory to obey. The man who is at a lower level but is moving onward toward perfection is living a more moral, a better life, is more fully carrying out Christ's teaching, than the man on a much higher level of morality who is not moving onward toward perfection.
It is in this sense that the lost sheep is dearer to the Father than those that were not lost. The prodigal son, the piece of money lost and found again, were more precious than those that were not lost.
The fulfillment of Christ's teaching consists in moving away from self toward God. It is obvious that there cannot be definite laws and rules for this fulfillment of the teaching. Every degree of perfection and every degree of imperfection are equal in it; no obedience to laws constitutes a fulfillment of this doctrine, and therefore for it there can be no binding rules and laws.
From this fundamental distinction between the religion of Christ and all preceding religions based on the state conception of life, follows a corresponding difference in the special precepts of the state theory and the Christian precepts. The precepts of the state theory of life insist for the most part on certain practical prescribed acts, by which men are justified and secure of being right. The Christian precepts (the commandment of love is not a precept in the strict sense of the word, but the expression of the very essence of the religion) are the five commandments of the Sermon on the Mount--all negative in character. They show only what at a certain stage of development of humanity men may not do.
These commandments are, as it were, signposts on the endless road to perfection, toward which humanity is moving, showing the point of perfection which is possible at a certain period in the development of humanity.
Christ has given expression in the Sermon on the Mount to the eternal ideal toward which men are spontaneously struggling, and also the degree of attainment of it to which men may reach in our times.
The ideal is not to desire to do ill to anyone, not to provoke ill will, to love all men. The precept, showing the level below which we cannot fall in the attainment of this ideal, is the prohibition of evil speaking. And that is the first command.
The ideal is perfect chastity, even in thought. The precept, showing the level below which we cannot fall in the attainment of this ideal, is that of purity of married life, avoidance of debauchery. That is the second command.
The ideal is to take no thought for the future, to live in the present moment. The precept, showing the level below which we cannot fall, is the prohibition of swearing, of promising anything in the future. And that is the third command.
The ideal is never for any purpose to use force. The precept, showing the level below which we cannot fall is that of returning good for evil, being patient under wrong, giving the cloak also. That is the fourth command.
The ideal is to love the enemies who hate us. The precept, showing the level below which we cannot fall, is not to do evil to our enemies, to speak well of them, and to make no difference between them and our neighbors. (fifth command)
All these precepts are indications of what, on our journey to perfection, we are already fully able to avoid, and what we must labor to attain now, and what we ought by degrees to translate into instinctive and unconscious habits. But these precepts, far from constituting the whole of Christ's teaching and exhausting it, are simply stages on the way to perfection. These precepts must and will be followed by higher and higher precepts on the way to the perfection held up by the religion.
And therefore it is essentially a part of the Christian religion to make demands higher than those expressed in its precepts; and by no means to diminish the demands either of the ideal itself, or of the precepts, as people imagine who judge it from the standpoint of the social conception of life.
