>1) How similar are both churches in terms of rituals and the sacraments?
Both works-based righteousness.
>2) Is there any reverence for Mary and the Saints? This is really important to me.

>3) How would you defend the beginning of the Anglican church? I'm not sure how to feel about Henry VIII doing the things he did.
It was founded on adultery.
>4) Any other pointers? Something else I should know?
1st Corinthians 6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
You must turn from your wickedness, as must the Episcopalian church! In many respects, their sin of willful deceit of the people is worse than your sin! Keep in mind that God once destroyed several cities over sodomy. How much worse will his wrath be on the Episcopalians, Methodists, Presbyterians, and (((others))) who promote this abomination?
