man at his creation, and treats of the image of God, freewill, and the primative integrity of nature.-Having finished the subject of creation, he proceeds to the conservation and government of all things, concluding the first book with a full discussion of the doctrine of divine providence.

II. But since man is fallen by sin from the state in which he was created, it is necessary to come to Christ. Therefore it follows in the Creed, "And in Jesus Christ, his only Son our Lord," &c.

So in the second book of the Institutes our Author treats of the knowledge of God as the Redeemer in Christ; and having shown the fall of man, leads him to Christ the Mediator. Here he states the doctrine of original sin-that man possesses no inherent strength to enable him to deliver himself from sin and the impending curse, but that, on the contrary, nothing can proceed from him, antecedently to reconciliation and renovation, but what is deserving of condemnation-Therefore, that, man being utterly lost in himself, and incapable of conceiving even a good thought by which he may restore himself, or perform actions acceptable to God, he must seek redemption out of himself, in ChristThat the Law was given for this purpose, not to confine its observers to itself, but to conduct them to Christ; which gives occasion to introduce an exposition of the Moral Law -That he was known, as the Author of salvation, to the Jews under the Law, but more fully under the Gospel, in which he is manifested to the world.-Hence follows the doctrine of the similiarity and difference of the Old and New Testament, of the Law and Gospel.-It is next stated, that, in order to the complete accomplishment of salvation, it was necessary for the eternal Son of God to become man, and that he actually assumed a real human nature:it is also shown how these two natures constitute one person-That the office of Christ, appointed for the acquisition and application of complete salvation by his merit and efficacy, is sacerdotal, regal, and prophetical.-Next follows the manner in which Christ executed his office, or actually performed the part of a Mediator, being an exposition of the Articles respecting his death, resurrection, and ascension to heaven.-Lastly, the Author shows the truth and

propriety of affirming that Christ merited the grace of God and salvation for us.

III. As long as Christ is separate from us, he profits us nothing. Hence the necessity of our being ingrafted into him, as branches into a vine. Therefore the doctrine concerning Christ is followed, in the third part of the Creed, by this clause, "I believe in the Holy Spirit," as being the bond of union between us and Christ.

So in the third book our Author treats of the Holy Spirit, who unites us to Christ-and consequently of faith, by which we embrace Christ, with his twofold benefit, free righteousness, which he imputes to us, and regeneration, which he commences within us, by bestowing repentance upon us.-And to show that we have not the least room to glory in such faith as is unconnected with the pursuit of repentance, before proceeding to the full discussion of justification, he treats at large of repentance and the continual exercise of it, which Christ, apprehended by faith, produces in us by his Spirit. He next fully discusses the first and chief benefit of Christ when united to us by the Holy Spirit that is, justification—and then treats of prayer, which resembles the hand that actually receives those blessings to be enjoyed, which faith knows, from the word of promise, to be laid up with God for our use.-But as all men are not united to Christ, the sole Author of salvation, by the Holy Spirit, who creates and preserves faith in us, he treats of God's eternal election; which is the cause that we, in whom he foresaw no good but what he intended freely to bestow, have been favored with the gift of Christ, and united to God by the effectual call of the Gospel.-Lastly, he treats of complete regeneration, and the fruition of happiness; that is, the final resurrection, towards which our eyes must be directed, since in this world the felicity of the pious, in respect of enjoyment, is only begun.

IV. But as the Holy Spirit does not unite all men to Christ, or make them partakers of faith, and on those to whom he imparts it he does not ordinarily bestow it without means, but employs for this purpose the preaching of the Gospel and the use of the sacraments, with the administration of all discipline, therefore it follows in the Creed,

"I believe in the Holy Catholic Church," whom, although involved in eternal death, yet, in pursuance of the gratuitous election, God has freely reconciled to himself in Christ, and made partakers of the Holy Spirit, that, being ingrafted into Christ, they may have communion with him as their head, whence flows a perpetual remission of sins, and a full restoration to eternal life.

So in the fourth book our Author treats of the Churchthen of the means used by the Holy Spirit in effectually calling from spiritual death, and preserving the church-the word and sacraments-baptism and the Lord's supperwhich are as it were Christ's regal sceptre, by which he commences his spiritual reign in the Church by the energy of his Spirit, and carries it forwards from day to day during the present life, after the close of which he perfects it without those means.

And as political institutions are the asylums of the Church in this life, though civil government is distinct from the spiritual kingdom of Christ, our Author instructs us respecting it as a signal blessing of God, which the Church ought to acknowledge with gratitude of heart, till we are called out of this transitory state to the heavenly inheritance, where God will be all in all.

This is the plan of the Institutes, which may be comprised in the following brief summary:—

Man, created originally upright, being afterwards ruined, not partially, but totally, finds salvation out of himself, wholly in Christ; to whom being united by the Holy Spirit, freely bestowed, without any regard of future works, he enjoys in him a twofold benefit, the perfect imputation of righteousness, which attends him to the grave, and the commencement of sanctification, which he daily increases, till at length he completes it at the day of regeneration or resurrection of the body, so that in eternal life and the heavenly inheritance his praises are celebrated for such stupendous mercy.

DEDICATION OF THE REVOLUTIONS OF THE HEAVENLY BODIES BY NICOLAUS COPERNICUS (1543)

TO POPE PAUL III

CAN easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected. For I am not so much in love with my conclusions as not to weigh what others will think about them, and although I know that the meditations of a philosopher are far removed from the judgment of the laity, because his endeavor is to seek out the truth in all things, so far as this is permitted by God to the human reason, I still believe that one must avoid theories altogether foreign to orthodoxy. Accordingly, when I considered in my own mind how absurd a performance it must seem to those who know that the judgment of many centuries has approved the view that the Earth remains fixed as center in the midst of the heavens, if I should, on the contrary, assert that the Earth moves; I was for a long time at a loss to know whether I should publish the commentaries which I have written in proof of its motion, Nicolaus Copernicus was born in 1473 at Thorn in West Prussia, of a Polish father and a German mother. He attended the university of Cracow and Bologna, lectured on astronomy and mathematics at Rome, and later studied medicine at Padua and canon law at Ferrara. He was appointed canon of the cathedral of Frauenburg, and in this town he died in 1543, having devoted the latter part of his life largely to astronomy.

The book which was introduced by this dedication laid the foundations of modern astronomy. At the time when it was written, the earth was believed by all to be the fixed centre of the universe; and although many of the arguments used by Copernicus were invalid and absurd, he was the first modern to put forth the heliocentric theory as "a better explanation." It remained for Kepler, Galileo, and Newton to establish the theory on firm grounds.

or whether it were not better to follow the example of the Pythagoreans and of some others, who were accustomed to transmit the secrets of Philosophy not in writing but orally, and only to their relatives and friends, as the letter from Lysis to Hipparchus bears witness. They did this, it seems to me, not as some think, because of a certain selfish reluctance to give their views to the world, but in order that the noblest truths, worked out by the careful study of great men, should not be despised by those who are vexed at the idea of taking great pains with any forms of literature except such as would be profitable, or by those who, if they are driven to the study of Philosophy for its own sake by the admonitions and the example of others, nevertheless, on account of their stupidity, hold a place among philosophers similar to that of drones among bees. Therefore, when I considered this carefully, the contempt which I had to fear because of the novelty and apparent absurdity of my view, nearly induced me to abandon utterly the work I had begun.

My friends, however, in spite of long delay and even resistance on my part, withheld me from this decision. First among these was Nicolaus Schonberg, Cardinal of Capua, distinguished in all branches of learning. Next to him comes my very dear friend, Tidemann Giese, Bishop of Culm, a most earnest student, as he is, of sacred and, indeed, of all good learning. The latter has often urged me, at times even spurring me on with reproaches, to publish and at last bring to the light the book which had lain in my study not nine years merely, but already going on four times nine. Not a few other very eminent and scholarly men made the same request, urging that I should no longer through fear refuse to give out my work for the common benefit of students of Mathematics. They said I should find that the more absurd most men now thought this theory of mine concerning the motion of the Earth, the more admiration and gratitude it would command after they saw in the publication of my commentaries the mist of absurdity cleared away by most transparent proofs. So, influenced by these advisors and this hope, I have at length allowed my friends to publish the work, as they had long besought me to do.
