O thou seeker after Truth! The question of the Trinity, since the time of His Holiness Christ until now, is the belief of the Christians, and to the present time all the learned among them are perplexed and confounded. All have confessed that the question is beyond the grasp of reason, for three cannot become one, nor one three. To unite these is impossible; it is either one or three. If we say the Essence of Divinity is divided, even in some aspects, division is one of the necessities of the contingent world and of generation, but the Ancient is holy (i.e., whole and indivisible). If we say that the Trinity was originally one and was later divided, change and transformation will be necessarily applied to the Essence of Oneness, and change and transformation are necessities of the contingent world and not of the Essence of Divinity. If we say this number is Ancient, three Ancients become necessary, and among the three some are distinguished which are also Ancients. In this wise five Ancients are the result, and among the five are those who are distinguished and thus nine Ancients become necessary, and so on ad infinitium.
Thus considered, Trinity is made a necessity, although the falsity of Trinity is evident. Furthermore, the signs of oneness are evident and plain in all existence. If thou shouldst gather all existent beings, thou wouldst be unable to find two alike in all states and qualities; of necessity there is a difference. Thus the signs of oneness are manifest and evident in all things. How much more is the Creator of all things!
