which man yields voluntary obedience to God Himself, by assenting to and co-operating with His grace, which he is able to resist.
Further, all those things are to be believed with divine and Catholic faith which are contained in the Word of God, written or handed down, and which the Church, either by a solemn judgment, or by her ordinary and universal magisterium, proposes for belief as having been divinely revealed.
And since, without faith, it is impossible to please God, and to attain to the fellowship of His children, therefore without faith no one has ever attained justification, nor will any one obtain eternal life, unless he shall have persevered in faith unto the end. And, that we may be able to satisfy the obligation of embracing the true faith and of constantly persevering in it, God has instituted the Church through His only begotten Son, and has bestowed on it manifest notes of that institution, that it may be recognised by all men as the guardian and teacher of the revealed Word; for to the Catholic Church alone belong all those many and admirable tokens which have been divinely established for the evident credibility of the Christian Faith. Nay, more, the Church by itself, with its marvellous extension, its eminent holiness, and its inexhaustible fruitfulness in every good thing, with its Catholic unity and its invincible stability, is a great and perpetual motive of credibility, and an irrefutable witness of its own divine mission.
And thus, like a standard set up unto the nations (Isaias xi. 12), it both invites to itself those who do not yet believe, and assures its children that the faith which they profess rests on the most firm foundation. And its testimony is efficaciously supported by a power from on high. For our most merciful Lord gives His grace to stir up and to aid those who are astray, that they may come to a knowledge of the truth; and to those whom He has brought out of darkness into His own admirable light He gives His grace to strengthen them to persevere in that light, deserting none who desert not Him. Therefore there is no parity between the condition of those who have adhered to the Catholic truth by the heavenly gift of faith, and of those who, led by human opinions, follow a false religion; for those who have received the faith under the magisterium of the Church can never have any just cause for changing or doubting that faith. Therefore, giving thanks to God the Father who has made us worthy to be partakers of the lot of the Saints in light, let us not neglect so great salvation, but with our eyes fixed on Jesus, the author and finisher of our Faith, let us hold fast the confession of our hope without wavering. (Hebr. xii. 2, and x. 23.)
