Wherefore were the heavens opened? To inform thee that at thy baptism also this is done, God calling thee to thy country on high, and persuading thee to have nothing to do with earth. And if thou see not, yet never doubt it. For so evermore at the beginnings of all wonderful and spiritual transactions, sensible visions appear, and such-like signs, for the sake of them that are somewhat dull in disposition, and who have need of outward sight, and who cannot at all conceive an incorporeal nature, but are excited only by the things that are seen: that so, though afterward no such thing occur, what hath been declared by them once for all at the first may be received by thy faith.
