This also is a part of the Church's teaching, that the world was made and took its beginning at a certain time, and is to be destroyed on account of its wickedness. But what existed before this world, or what will exist after it, has not become certainly known to the many, for there is no clear statement regarding it in the teaching of the Church. (From the preface)

There is much the Church does not know. This ignorance encompasses both the natural and spiritual domains.

Believers can cordially - or not - disagree regarding their speculations, studies, and findings.

But in this and much more Origen offers it is helpful to recognize where authoritative guidance does not exist.
