Father Stephanos illustrates how immeasurably profound and wondrous Divine Liturgy and receiving the body and blood of Christ is with 200 stories of the visible in breaking of the heavenlies during the Liturgy. While extolling the wonder of it all, he also educates in regard to the details of the Liturgy. He makes some absolutist statements in a few places that I question, but overall, it is a very inspiring book. It's intimidatingly big, but it's very much worth the read.
