One of the tragedies of the Protestant Reformation is that it resulted in a lot of Protestants squeamish about talking about the Virgin Mary, and a lot of Catholics squeamish about talking about grace and predestination (in both cases, out of a fear of the other side's perceived excesses). In reality, if you want to know what God's predestination looks like, look to the Virgin Mary. And you can't understand Mary without understanding predestination.
I've been gone for the better part of the last two weeks because of World Youth Day. It was emotionally and physically exhausting, but an incredibly rich experience.
Does Mary's sinlessness eliminate her need for a Savior or for grace? Or is her sinlessness the result of those? Plus, what does Mary's sinlessness mean for the salvation of angels or the Saints in Heaven?
