From the above it will at once be seen what is the right and what the wrong use of the mass, what is the worthy and what the unworthy preparation for it. If the mass is a promise, as has been said, it is to be approached, not with any work or strength or merit, but with faith alone. For where there is the word of God Who makes the promise, there must be the faith of man who takes it. It is plain, therefore, that the first step in our salvation is faith, which clings to the word of the promise made by God, Who without any effort on our part, in free and unmerited mercy makes a beginning and offers us the word of His promise. For He sent His Word, and by it healed them [Ps. 107:20]. He did not accept our work and thus heal us. God's Word is the beginning of all; on it follows faith, and on faith charity; then charity works every good work, for it worketh no ill, nay, it is the fulfilling of the law [Rom. 13:10]. In no other way can man come to God and deal with Him than through faith; that is, not man, by any work of his, but God, by His promise, is the author of salvation, so that all things depend on the word of His power, and are upheld and preserved by it [Heb. 1:3], with which word He begat us, that we should be a kind of firstfruits of His creatures [Jas. 1:18]. Thus, in order to raise up Adam after the all, God gave him this promise, addressing the serpent: "I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel." [Gen. 3:15] In this word of promise Adam, with them that were his, was carried as it were in God's bosom, and by faith in it he was preserved, patiently waiting for the woman who should crush the serpent's head, as God had promised. And in that faith and expectation he died, not knowing when or in what guise she would come, yet never doubting that she would come. For such a promise, being the truth of God, preserves, even in hell, those who believe it and wait for it. After this came another promise, made to Noah--to last until the time of Abraham--when a bow was set as a sign in the clouds [Gen. 9:12], by faith in which Noah and his descendants found a gracious God. After that He promised Abraham that all nations should be blessed in his seed [Gen. 12:3]; and this is Abraham's bosom, into which his posterity was carried [Luke 16:22]. Then to Moses and the children of Israel, and especially to David, He gave the plain promise of Christ [Deut. 18:18], thereby at last making clear what was meant by the promise to them of old time [2 Sam. 7:6]. And so it came finally to the most complete promise of the new testament, in which with plain words life and salvation are freely promised, and granted to such as believe the promise. And He distinguished this testament by a particular mark from the old, calling it the "new testament." [Luke 22:20] For the old testament, which He gave by Moses, was a promise not of remission of sins or of eternal things,
