"But now ye seek to kill me, a man that hath told you the truth...."—John viii. 40.
"And ye shall know the truth, and the truth shall make you free."—John viii. 32.
God must be worshiped in truth. All the doctrine will be made plain by the Spirit of Truth. Do as I command you, and you will know whether what I say is the truth.
No evidence was brought to prove the doctrine, except the truth and its harmony therewith. The whole substance consisted in learning the truth and in following its guidance, drawing nearer and nearer to it in the affairs of everyday life.
According to this doctrine, there is no mode of action that can justify a man or make him righteous; as regards interior perfection we have only the image of truth, in the person of Christ, to win our hearts, and outward perfection is expressed by a realization of the Kingdom of God. In order to fulfil the doctrine it needs but to take Christ for our model, and to advance in the direction of interior perfection by the road which has been pointed out to us, as well as in that of exterior perfection, which is the establishment of the Kingdom of God. The degree of human happiness, whether it be more or less, depends, according to this doctrine, not on the degree of perfection at which it arrives, but on the comparative rate of progress toward that perfection.
The advance toward perfection of Zacchæus the publican, of the adulteress, of the thief on the cross, is, according to this doctrine, better than the stagnation of the righteous Pharisee. The shepherd rejoices more over the one sheep which was lost and is found than over the ninety and nine which are in the fold. The prodigal returned, the piece of money which was lost and is found, is more precious unto God than that which was never lost.
According to this doctrine, each state is but a step on the road toward the unattainable interior and exterior perfection, and therefore it has no significance in itself. The progress of this movement toward perfection is its merit; the least cessation of this movement means the cessation of good works.
"Let not thy left hand know what thy right hand doeth," and "No man, having put his hand to the plow, and looking back, is fit for the kingdom of God." "Rejoice not that the spirits are subject unto you; but rather rejoice, because your names are written in heaven." "Be ye therefore perfect, even as your Father which is in heaven is perfect." "Seek ye first the kingdom of God and his righteousness."
The fulfilment of the doctrine lies in a continual progress toward the attainment of a higher truth, and in the growing realization of that truth within one's self, by means of an ever increasing love; as well as in a more and more keen realization of the Kingdom of God in the world around us. It is evident that the doctrine that appeared in the midst of the Hebrew and pagan world could not be accepted by the majority of men, who lived a life so totally unlike the one prescribed by this new doctrine; and even those who did accept it could not comprehend its full meaning, because of its contradiction of all former ideas.
