Christ's teaching only then has force, when it demands full perfection, that is, the blending of God's essence, which abides in the soul of every man, with the will of God,--the union of the son and the Father. Only this liberation of the son of God, who lives in every man, from the animal, and his approximation to the Father form life according to Christ's teaching. The existence of the animal in man, of nothing but the animal, is not the human life. Life according to the will of God alone is also not the human life. The human life is the resultant from the animal and the divine lives, and the more this resultant approaches the divine life, the more there is of life. Life, according to the Christian teaching, is a motion toward divine perfection. No condition, according to this teaching, can be higher or lower than another. Every condition, according to this teaching, is only a certain step, indifferent in itself, toward the unattainable perfection, and so in itself forms neither a greater nor a lesser degree of life. The increase of life, according to this teaching, is only an acceleration of motion toward perfection, and so the motion toward perfection of the publican Zacchæus, of the harlot, of the robber on the cross, forms a higher degree of life than the immovable righteousness of the Pharisee. And so there can be no obligatory rules for this teaching. A man who stands on a lower step, in moving toward perfection, lives more morally and better, and better performs the teaching, than a man who stands on a much higher stage of morality, but who does not move toward perfection. In this sense the lost sheep is dearer to the Father than one which is not lost. The prodigal son, the lost coin which is found again, are dearer than those which were not lost. The fulfilment of the teaching consists in the motion from oneself toward God. It is evident that for such a fulfilment of the teaching there can be no definite laws and rules. All degrees of perfection and all degrees of imperfection are equal before this teaching; no fulfilment of the laws constitutes a fulfilment of the teaching; and so, for this teaching there are, and there can be, no rules and no laws.
