A footnote in Origen’s Commentary on Romans:

Erasmus’s [Desiderius Erasmus’] clarification of this passage (CWE 56:11) is most helpful:
“Origen seems to have thought that ‘predestine’ has a double aspect of futurity and ‘destine’ merely a single. For if I ‘destine’ a bride for a son of mine already born, the person for whom I destine belongs to the present time, what I am destining belongs to the future. But if I resolve to dedicate to the study of theology the son who will be born first, then both the person and the thing belong to future time; and Origen would have the world ‘predestine’ refer to cases ofthe latter type.”
