Okay he has damned Eastern Catholics to hell seemingly which the most hard line Feeneyite which tremble at doing so.Even 70 years ago as a child, I thought the teaching "outside the Church (Roman Catholic, of course) there is no salvation" was a bit OTT. In my mature olds age, I know it is not just OTT but ridiculous; just like the idea that an innocent unbaptised baby would stay in Limbo and much worse,could not -and wasn't - buried in sacred ground; just as a bishop's ruling that anyone who went to a certain dancing venue committed a mortal sin by just being there; just as, just as a whole pile of similar Ráiméis.
Field Marshall, if you're serious, get a grip and realise that God cannot be a small-minded bigot. He's no longer behind the door with a hammer to belt every wrong-doer . He has to be a God of Love - without the hammer.
However while I definitely believe that the Byzantine and Non-Chalcedonian Orthodox can be saved and even reach Holiness (they of course have valid Sacraments and so are part of the Church in many ways), and while I hope that God will Mercy on genuinely Believing Protestants those who have rejected Christ out and out, how can they be saved by Him? They have made their choice- no one is forcing Freemasons to be continue being Freemasons and Quakers to still be Quakers. They are so because they have rejected God's Love, sided with His principle enemy and so will have a share in that enemy's lot.
