" Jesus came to bring salvation to all men, yet he will be a sign of contradiction because some people will obstinately reject him - and for this reason he will be there ruin. But those who accept him with faith Jesus will be their salvation, freeing them from sin in this life and raising them up to eternal life."
The last words of the prophecy, “that thoughts out of many hearts may be revealed”, link up with the first statement: uprightness or perversity will be demonstrated by whether one accepts or rejects Christ.
This is one interpation taken from the Navarre Bible. Here is another.
“that many throught their own wilful blindness and obstinancy would not believe in Christ, nor receive his doctrine, which therefore would be ruin to them; but to others a ressurection, by their believing in him, and by obeying his commandments.”
Douay Rheims footnote.
I often pray the Dolors of Mary, yet this is the first time I researched Simeons words.
