ON THIS EARTH---we do not grasp the ETERNAL TRUTH.  We cannot comprehend God who IS ETERNAL TRUTH.  God can only be loved and enjoyed---which is the best way to know God and respond to God.  

As one who teaches Church history, we see the church teaching many things that were colored by the times, by politics, by the hierarchy's desire for greater power.  For example, we tried to know and explain God through objectified knowledge.  This is crazy!  That is why we have so many mass-produced fundamentalists and practical agnostics inside the church---and sincere atheists outside of it.

The church of 1017 does not speak to us any more than the concept of a flat earth does.  Our Church has recognized that the Protestants have much good to say to us and much truth as well.  The Holy Spirit doesn't fail to inspire any who sincerely pray and that includes any man or woman of good will.
