I wanted to share these words from the recent issue of Dinoscopus - an email newsletter with the thoughts/writings of Bishop Richard Williamson. Emphasized items are underlined:
Now it is true that any one sacrament administered in real life will have been either valid or invalid. There are no more shades between valid and invalid than there are between pregnant and not pregnant. But if we consider the Conciliar sacraments being all the time administered throughout the Newchurch as a whole, we can only say some are valid, some are invalid, but they have all been placed on a slide towards invalidity by the Conciliar Rites' total thrust to replace the religion of God with the religion of man. That is why the Newchurch is on its way to disappearing altogether, and why the Society of St. Pius X can in no way allow itself to be absorbed into it.
Meanwhile, as to just how far down the slide is this or that priest, or even the Newchurch as a whole, I will apply the great principle of St. Augustine: "In things certain, unity; in things doubtful, liberty; in all things, charity". And within the framework of certainties such as, within the Newchurch neither already nothing, nor everything still, is Catholic, I mean to extend to my fellow-Catholics the same liberty to judge of things uncertain as I hope they will extend to me. Mother of God, obtain the rescue of the Church !
