I was honored to receive an email from Nate Bobbett, who's the Antioch pastor who delivered the message I referred to below.
Nate had a few explanatory comments on the message he preached, and Antioch's position on the Lord's Supper:
Antioch officially stands on a doctrinal continuum somewhere between Calvin and Luther – when it comes to The Lord’s supper. We believe there is power and there is presence. But officially, we would say that there is not actually Jesus’ body in the elements. ...
And personally I am comfortable with believers taking different stands on this issue. Of greater importance is that we come together with reverence, and that we come together often around the Lord’s table, recognizing his great power and presence in this sacrament!
Part of my response:
I think we're all growing and mindful of the fact that even if it's not the literal body and blood, it certainly is a holy sacrament -- and an incredible honor.
