Yeah, my vague memory is that this book was very Vatican II-sounding and was suggesting some kind of religious union with Protestants. Don't hold me to that though.
Interestingly, Michael Hoffman, who is also fixated on the Jєωιѕн question, is all for religious liberty. Maybe hatred for the Jews, rather than simple realism about their anti-Christ activities in the world, blinds you. Or maybe there are infiltrators who portray themselves as anti-Jew to win the confidence of certain Catholics, at which point they then slip them some misleading opinions.
