Actually, in the last 20 or 30 years there's been a serious narrowing of acceptable religious practice within The (official) Episcopalian Church (TEC). More and more, if a pastor objects to the official Politically Correct line (female priests & bishops....as well as--much worse--active homosexual priests and bishops....) dictated from the NYC offices of TEC, they will be marginalized or even force to leave. In particular, they have squeezed out traditional conservative/orthodox Christians--either from the evangelical/biblical side (so called "low church) or (and especially) the Anglo-Catholic ("high church") side.
Very few Anglo-Catholic congregations remain Episcopal...
Over the last 20 or 30 years, membership of TEC has reduced by over 30%--and the average age of members today is somewhere over 60. TEC is literally dying.
FWIW, I also perceive, in substance, the message of the article is occurring.
It troubles me that there has been a push in the recent past to unify Islam with RCC, if not explicitly, then at least by appearance. The recent moves in the Middle East from Africa to Indonesia appear to be an effort to unite Islam from Shia/Sunni differences.
While Catholicism expresses many outstanding doctrines, it also is one of the most visible worldly perceptions of Christianity. This makes it ripe for targeting by the Adversary, to encroach and attempt to counterfeit from within.
IMHO, our first priority is to remain in faith through Christ in all things and let His Will prevail.
