During the exchange of the Peace in the Orthodox Divine Liturgy it had been my custom to greet those around me by saying, “Christ is in our midst!”, expecting the reply (and giving as the reply when the greeting was given to me) “He is and ever shall be!” I was therefore quite surprised when the (now late) Fr. Michael Oleksa commented to me, “Actually, that’s not the correct reply: we should reply by saying, ‘He is and shall be”. I immediately looked it up in the service book and found (unsurprisingly, given Fr. Michael’s learning) that he was correct. But what’s the difference? And does it really matter? Isn’t it saying the same thing?
