St Cyril of Jerusalem:

EXCERPT FROM THE CATECHETICAL LECTURES

On Baptism

We may not receive Baptism twice or thrice; else it might be said, Though I have failed once, I shall set it right a second time: whereas if thou fail once, the thing cannot be set right; for there is one Lord, and one faith, and one baptism: for only the heretics are re-baptized, because the former was no baptism.

For God seeks nothing else from us, save a good purpose. Say not, How are my sins blotted out? I tell thee, By willing, by believing. What can be shorter than this? But if, while thy lips declare thee willing, thy heart be silent, He knoweth the heart, who judgeth thee. Cease from this day from every evil deed. Let not thy tongue speak unseemly words, let thine eye abstain from sin, and from roving after things unprofitable.

Let thy feet hasten to the catechisings; receive with earnestness the exorcisms: whether thou be breathed upon or exorcised, the act is to thee salvation. Suppose thou hast gold unwrought and alloyed, mixed with various substances, copper, and tin, and iron, and lead: we seek to have the gold alone; can gold be purified from the foreign substances without fire? Even so without exorcisms the soul cannot be purified; and these exorcisms are divine, having been collected out of the divine Scriptures. Thy face has been veiled, that thy mind may henceforward be free, lest the eye by roving make the heart rove also. But when thine eyes are veiled, thine ears are not hindered from receiving the means of salvation. For in like manner as those who are skilled in the goldsmith's craft throw in their breath upon the fire through certain delicate instruments, and blowing up the gold which is hidden in the crucible stir the flame which surrounds it, and so find what they are seeking; even so when the exorcists inspire terror by the Spirit of God, and set the soul, as it were, on fire in the crucible of the body, the hostile demon tees away, and there abide salvation and the hope of eternal life, and the soul henceforth is cleansed from its sins and hath salvation. Let us then, brethren, abide in hope, and surrender ourselves, and hope, in order that the God of all may see our purpose, and cleanse us from our sins, and impart to us good hopes of our estate, and grant us repentance that bringeth salvation. God hath called, and His call is to thee.
