Origen Against Celsus by Origen
Chapter XXI. The Scriptures which are current in the Churches of God do not speak of |seven|à
The Scriptures which are current in the Churches of God do not speak of |seven| heavens, or of any definite number at all, but they do appear to teach the existence of |heavens,| whether that means the |spheres| of those bodies which the Greeks call |planets,| or something more mysterious. Celsus, too, agreeably to the opinion of Plato, asserts that souls can make their way to and from the earth through the planets; while Moses, our most ancient prophet, says that a divine vision was presented to the view of our prophet Jacob, -- a ladder stretching to heaven, and the angels of God ascending and descending upon it, and the Lord supported upon its top, -- obscurely pointing, by this matter of the ladder, either to the same truths which Plato had in view, or to something greater than these. On this subject Philo has composed a treatise which deserves the thoughtful and intelligent investigation of all lovers of truth.
