When I used to serve an Episcopal Church, one of the liturgical differences that stood out to me the most was the fact that we didn't have a prayer of confession during Easter. Don't get me wrong; I totally appreciate the theology behind this, but as a cradle Presbyterian, it just feels wrong not to confess our total depravity every week, even on the day that we celebrate the divine act that ensured our salvation. So I always include it in every liturgy that I write.
