Catena Aurea · Lukasevangelium 2
And Joseph and his mother marvelled at those things which were spoken of him. And Simeon blessed them, and said unto Mary his mother, Behold, this child is set for the fall and rising again of many in Israel; and for a sign which shall be spoken against; (Yea, a sword shall pierce through thy own soul also,) that the thoughts of many hearts may be revealed.
(de occ. Dom. non occ.) But it is not meant that she alone was concerned in that passion, for it is added, that the thoughts of many hearts may be revealed. The word that marks the event; it is not used causatively; for when all these events took place, there followed the discovery of many men’s intentions. For some confessed God on the cross, others even then ceased not from their blasphemies and revilings. Or this was said, meaning that at the time of the passion the thoughts of men’s hearts should be laid open, and be corrected by the resurrection. For doubts are quickly superseded by certainty. Or perhaps by revealing may be meant, the enlightening of the thoughts, as it is often used in Scripture.
