We see, likewise, how all things of the same species incline naturally to the same end; as all heavy things tend towards their centre. Therefore, Christ must be the Last End of human life, since nothing has been pursued by men with the same ardour and constancy, that they have shown in following Him. This is the reason why Christians are so closely united together; for we see that they love Jesus Christ above all things. For His sake they likewise love each other, of whatsoever race and country they may be; and the more their faith in Christ increases, the stronger grows their brotherly love. This could not be the case were their faith not true. For fallacy and error cause, not harmony, but discord.

Again. The soul enjoys greater happiness in proportion as, by love and contemplation, it draws nearer to its last end. But the happiness enjoyed by Christians far surpasses all pleasures of understanding and sense. This truth is proved by the invincible constancy of the martyrs, who went to death rejoicing and exulting; by the numberless monks and hermits who, relinquishing all things, and living in the practice of the greatest austerity, have yet enjoyed incomparable happiness; and by the numerous philosophers who have found such delight in the study of Holy Scripture, that, in order to devote themselves to it, they have abandoned every other branch of learning. Hence we see that the joy which souls find in Christ exceeds all other happiness. If, then, felicity be synonymous with proximity to our last end, Christ, in whom all happiness is found, must be the Last End of human life.

In order to comprehend, collectively, all the properties of our Last End we reason thus. As all things of the same species tend naturally to the same end, be it proximate or ultimate, it follows that men, who are all of the same species, must be fitted for some one thing which is the common end of human life. Now, all men agree in professing that they tend towards a last end; but they differ as to that wherein their last end is to be found. But since the happiness of mankind consists in the act of understanding, it is natural to conclude that this last end is to be found in that thing, towards which they who live the most rationally and whose affections are the most purified do uniformly incline; that to which they steadfastly adhere, loving it better than themselves; delighting in it; drawing from it sanctity of ways and brightness of heavenly life; and being raised by its influence so far above this world, that, in comparison with their end, they repute all earthly things as worthless. Now, as all these wonderful effects have never been produced in man by any, save by Christ Crucified, He must be the Last End of human life.

But why do we insist on so self-evident a truth knowing, as we do, that it is the property of Good to communicate itself, and that the graces and blessings diffused by Christ over mankind are absolutely unequalled? His coming has purged the world from error, filled it with sanctity and virtue, and communicated to all His followers happiness which no earthly thing could give. His supreme goodness is further shown by the promptitude and liberality wherewith He not only forgives sinners, but so enriches them with His gifts, that where sin did abound, grace has much more abounded, and they who return to Him from their sins are enabled to lead a virtuous life and enjoy their pristine peace and happiness, whereas they who forsake Him lose all tranquillity of mind. What further proof do we require that Christ is the Supreme Good, and the Last End of man?

CHAPTER XVI.
THE TRUTH OF CHRISTIANITY IS PROVED BY THE POWER, WISDOM, AND GOODNESS OF CHRIST, CONSIDERED COLLECTIVELY.

We may sum up in a few words what has been already said about the power, the wisdom, and the goodness of Christ. Had Christ not been God, He would have been the most proud and the most foolish of men. And if (as some hold) the assertion of His Divinity was not made by Himself but by His disciples, how can a religion of such goodness, wisdom, and power, be the outcome of such a falsehood? If Christ be not God, who is God? God preserves and governs all inferior things by the requisite means; and, as no means are so suitable for the attainment of a virtuous life as the Faith and love of our Saviour Jesus Christ, we must either acknowledge that He is the true means whereby we attain beatitude, or must hold, with fatalists, that things happen by chance; and we must end in denying the existence of God.

Again. If there be any true religion in the world; and if no religion be supported by such arguments and undeniable proofs as is the Christian religion; where, save in Christianity, are we to seek the true religion?

Further. No religion has endured the constant and cruel persecution inflicted on Christianity. Other religions, or rather superstitions, have never roused in the world the hatred excited by the Faith of Christ. Yet, in spite of this fact, other religions which persecuted Christianity, have died out, of themselves, without being persecuted. Christianity has only flourished, and waxed stronger, by means of its conflicts. How do we account for this fact, if Christianity be untrue?

We must remember, likewise, that they who have persecuted Christians have been, not good and upright men, but men of infamous life. Is not this a further proof of the truth of our religion?
