Look, you have presented nothing to show that Bishop Gao suffered from "pressure from the Vatican to merge with heretic bishops loyal to the Chinese government". That is simply untrue. Canadian bishops, Levada, et al are no more "the Vatican" then you or me, if they in fact pressured Bishop Gao, which we have seen no evidence of, but only of their disobedience to Rome by welcoming CCPA clergy - which does not constitute Vatican pressure on Bishop Gao to "merge with heretic bishops".
I have never attempted to do so. You're barking up the wrong tree.
