From St. Cyril of Jerusalem, "Catechetical Lectures," Lecture V: On Faith. I have not included most of the footnotes, which I find a bit helpful. The whole article is fantastic, but it would be too much to reproduce in full here.
10. For the name of Faith is in the form of speech one, but has two distinct senses. For there is one kind of faith, the dogmatic, involving an assent of the soul on some particular point: and it is profitable to the soul, as the Lord saith: He that heareth My words, and believeth Him that sent Me, hath everlasting life, and cometh not into judgment (John v. 24.): and again, He that believeth in the Son is not judged, but hath passed from death unto life (John iii. 18; v. 24.). Oh the great loving-kindness of God! For the righteous were many years in pleasing Him: but what they succeeded in gaining by many years of well-pleasing, this Jesus now bestows on thee in a single hour. For if thou shalt believe that Jesus Christ is Lord, and that God raised Him from the dead, thou shalt be saved, and shalt be transported into Paradise by Him who brought in thither the robber. And doubt not whether it is possible; for He who on this sacred Golgotha saved the robber after one single hour of belief, the same shall save thee also on thy believing (Luke xxiii. 43).
11. But there is a second kind of faith, which is bestowed by Christ as a gift of grace. For to one is given through the Spirit the word of wisdom, and to another the word of knowledge according to the same Spirit: to another faith, by the same Spirit, and to another gifts of healing (1 Cor. xii. 8, 9.). This faith then which is given of grace from the Spirit is not merely doctrinal, but also worketh things above man’s power. For whosoever hath this faith, shall say to this mountain, Remove hence to yonder place, and it shall remove (Mark xi. 23.). For whenever any one shall say this in faith, believing that it cometh to pass, and shall not doubt in his heart, then receiveth he the grace.
And of this faith it is said, If ye have faith as a grain of mustard seed (Matt. xvii. 20.). For just as the grain of mustard seed is small in size, but fiery in its operation, and though sown in a small space has a circle of great branches, and when grown up is able even to shelter the fowls (Matt. xiii. 32.); so, likewise, faith in the swiftest moment works the greatest effects in the soul. For, when enlightened by faith, the soul hath visions of God, and as far as is possible beholds God, and ranges round the bounds of the universe, and before the end of this world already beholds the Judgment, and the payment of the promised rewards. Have thou therefore that faith in Him which cometh from thine own self, that thou mayest also receive from Him that faith which worketh things above man.
