The Episcopal Church follows the Revised Common Lectionary. That means that on any given Sunday, Christ Church will be reading the same Scripture readings as all other denominations and congregations who follow this lectionary! The schedule of Sunday Scripture readings can be found here.
An excellent resource (though admittedly the viewpoint of a single person) can be found in this commentary on our Sunday lectionary by a layman at St. Timothy's Episcopal Church in Centennial. Dennis Haugh earned his PhD in Biblical Studies in the University of Denver/Iliff School of Theology joint program. Clicking on the link above will lead you to a page where you can view, and download if you like, a PDF containing the Scripture readings and commentary.
