The third ternary circle we call Moral, and it belongeth to the works that are done by us, the which commence in the credit that the Lord God willeth to give them, for He doeth them chiefly, and we are instruments set in the midst, which He useth at His pleasure, working His will and accomplishing them as He pleaseth; and for the confirming of this it is written in the Gospel of St. Luke that if we do all that is commanded of us, we may know that we are unprofitable servants, for we only perform that to which we are constrained. And of a certainty all that we can do is vanity, since it can be accomplished without us, and we deserve nothing in it except as far as it pleaseth the Creator to grant us of His mercy, by doing us the excellent favour of making use of us in His actions, and willing that we be instruments in some of the things that He doeth. And this pleaseth His goodness, because He findeth in us some work of His by which we may earn a good reward. And therefore wise men perceiving this infinite mercy, that maketh them to be what they are, and understanding that all good works proceed from Him by His imperial pleasure, confess that they deserve nothing for what they may do; and they labour to fulfil this circle, so that their every act may terminate in that beginning where it commenced. * * * * * And because you, most high and excellent Prince, among mortals, and according to my thinking, most virtuous lord, chiefly for the sake of thanksgiving didst order me, Gomez Eannes de Azurara, your servant and creature, and through your munificence, Knight and Commander in the Order of Christ, to compose this book, with good reason it seemeth fit that in thanksgiving I should make an end of it. And since the Apostle Saint Paul teacheth us in all things to give thanks to God, as is contained in the Epistle which he sent to the men of Thessalonica; so, making the circle of my work, I put the final term in that Helper who was invoked by my will in the commencement; and I offer to the Infinite Personal Ternary whatsoever thanks I can, for I have not the power to give as many as I owe: firstly, to the Father super-essential, from whom universally proceed all things, to Him I give thanks for the talent he gave me to commence this work; and then to the Son super-spiritual, who had no commencement of being, to Him I give thanks for the help He bestowed on me to continue what I had commenced; and then to the Holy Spirit super-natural, from whom we have all good things by His benevolence, to Him I give thanks for the inspiration by which He moved your Highness to lay this command upon me and not on any other of your countrymen and subjects, of whom you could have had many. And jointly to all the Three Persons who compose the Ineffable Trinity and Super-essential Unity, our one only true Lord God, I offer thanks for the ending, because all things have concluded better than I thought before. * * * * *
