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 Zacchaeus, 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.
