The center of Episcopal teaching is the life and resurrection of Jesus Christ.[70] The basic teachings of the church, or catechism, includes:
* Jesus Christ is fully human and fully God. He died and was resurrected from the dead.
* Jesus provides the way of eternal life for those who believe.
...
* The Old and New Testaments of the Bible were written by people "under the inspiration of the Holy Spirit."
Do I have the wrong Episcopal Church?
That last line especially deals with revelation, which is the main device through which the divine is said to make itself known.
(I'm not so presumptuous as to tell you what you believe; it just looks like what you said is contradictory)
EDIT: Is this some trick of terminology in which you guys can't really verify the core tenets of the religion, so you say you don't know them to be true, but instead believe (read: have faith in) them to be true?
Double checking my book of common prayer I can say that while that summery of our catechism isn't strictly speaking a lie, it is certainly misleading. It was probably put up by one of the more conservative members of our church that does personally view our doctrine that way. The catechism's actual answers on some of those things such as hell are actually tame enough to make just stating that we believe in it fairly misleading.
The official Episcopal stance is that the
Nicene creed and the
Apostles' creed are the sum of required belief to be a Christian. It is notable that these two creeds are statements of belief and not fact or knowledge. We do have a catechism, but unlike many churches it is not a statement of official dogma.
Here's a quote from the book of common prayer preceding the catechism.
"It is a commentary on the creeds, but is not meant to be a complete statement of belief and practices; rather, it is a point of departure for the teacher, and it is cast in the traditional question and answer form for ease of reference."
It is the Episcopal stance that one is allowed and encourage to consider and interpret the creeds for themselves.
Sometimes this can lead to people with
radically different views worshiping together.
And while many churches might not officially have this practice of personal interpretation, it is never the less very common in any number of denominations. It is a fairly recent occurrence in the history of the church that the Bible was viewed as the word of god, literal, infallible, and complete.
