5 If, therefore, the soul remembers nothing of what took place in a former state of existence, but has a perception of those things which are here, it follows that she never existed in other bodies, nor did things of which she has no knowledge, nor [once] knew things which she cannot [now mentally] contemplate. But, as each one of us receives his body through the skilful working of God, so does he also possess his soul. For God is not so poor or destitute in resources, that He cannot confer its own proper soul on each individual body, even as He gives it also its special character.
And therefore, when the number [fixed upon] is completed, [that number] which He had predetermined in His own counsel, all those who have been enrolled for life [eternal] shall rise again, having their own bodies, and having also their own souls, and their own spirits, in which they had pleased God. Those, on the other hand, who are worthy of punishment, shall go away into it, they too having their own souls and their own bodies, in which they stood apart from the grace of God. Both classes shall then cease from any longer begetting and being begotten, from marrying and being given in marriage; so that the number of mankind, corresponding to the fore-ordination of God, being completed, may fully realize the scheme formed by the Father.
