The Episcopal "church" today is beyond a disgrace. It is no longer a case that the Gospel is no longer being preached from Episcopal pulpits. Nowadays, there is no shortage of Episcopal bishops and priests affirmatively trying to lead people away from Christ Jesus.
Satan is in complete control, as it were.
So many millions in England have walked away from Christianity. Is that because Anglicanism led them away, or because the English people pushed Anglicanism to the left?
