Cf. S. Ambros. De Mysteriis, c. ii. 7: “Ad orientem converteris; qui enim renunciat diabolo ad Christum convertitur:” “Where he plainly intimates.…that turning to the East was a symbol of their aversion from Satan and conversion unto Christ, that is, from darkness to light, from serving idols, to serve Him, who is the Sun of Righteousness and Fountain of Light” (Bingh. Ant. xi. vii. 7).
