49 But inasmuch as Simeon endured to carry on his weak arms that Majesty which the creatures could not endure, it is evident that his weakness was made strong by the strength which he carried. For at that time Simeon also along with all creatures was secretly upheld by the almighty strength of the Son. Now this is a marvel, that outwardly it was he that was strengthened that carried Him Who strengthened him; but inwardly it was the strength that bore its bearer. For the Majesty straitened itself, that they who carried it might endure it; in order that as far as that Majesty stooped to our littleness, so far should our love be raised up from all desires to reach that Majesty.
