If rhythmic, hand-clapping, dancing-in-the-aisles church music would turn off, frighten or scandalize some of us (we who too often fear those kinds of expressions of emotional enthusiasm as if they were demons from the depths), it's not too had to see how our sometimes quiet, meditative, reflective piety might look frosty and scary to someone from another Christian tradition.
You do understand, Pastor Weedon, that God's grace and forgiveness can be mediated without having weekly "the body and blood of Christ"? You do understand that millions of Christians (including our forbears even in Luther's time) are faithful Christians communing maybe once a month, once a quarter or once a year?
They are not missing the grace of God or the forgiveness of sins.
