It's not as mind shatteringly beautiful as Veritatis Splendor but it's very very good.
Ah, yes, Salvifici Doloris, a beautiful apostolic letter!
But it's better translated as Salvific Suffering...as it is not simply referring to physical or psychic pain, but all manner of suffering.
(Oh, and by the way) 2 Cor 1:5 For as we share abundantly in Christ's sufferings, so through Christ we share abundantly in comfort too.
Col 1:24 Now I rejoice in my sufferings for your sake, and in my flesh I complete what is lacking in Christ's afflictions for the sake of his body, that is, the church
It's truly amazing what scripture actually says when one takes the time to read it!
OK, I remember. The phrase for Sorrows is Delarosa or something like that.
Another oops!
