18.

And the Spirit, indeed, continues to this day invisible to men, as the Lord says, "The Spirit breathes where He will; and thou knowest not whence He cometh, or whither He goeth." ¹ But in the beginning of the mystery of the faith and of spiritual baptism, the same Spirit was manifestly seen to have sat upon the disciples as it had been fire. Moreover, the heavens being opened, to have descended upon the Lord like a dove; because many things, yea, almost all things which were to be, are manifest--which, however, were only invisible nevertheless,--now also are shown to the eyes and to the incredulity of men, either partially, or at times, or in figure, for the strengthening and confirming of our faith. But neither should I omit that which the Gospel well announces. For our Lord says to the paralytic man, "Be of good cheer, my son, thy sins are forgiven thee," ² that He might show that hearts were purified by faith for the forgiveness of sins that should follow. And this remission of sins that woman also which was a sinner in the city obtained, to whom the Lord said, "Thy sins are forgiven thee." ³ And when they who were reclining around began to say among themselves, "Who is this that forgiveth sins?" ⁴ --because concerning the paralytic the scribes and Pharisees had murmured crossly--the Lord says to the woman, "Thy faith hath made thee whole; go in peace." ⁵ From all which things it is shown that hearts are purified by faith, but that souls are washed by the Spirit; further, also, that bodies are washed by water, and moreover that by blood we may more readily attain at once to the rewards of salvation.
