Great Video on Eucharistic Theology

 Mr. Jonah Saller's "Mere Catholicity" YouTube channel is worth checking out.  He is a very thoughtful Anglican layman who is well-read.  In this video he lays out an approach to the Real Presence of Christ in the Lord's Supper that both takes on board the Lutheran (and Roman Catholic & Eastern Orthodox) concern that the Spirit actually does do something objectively to the elements themselves, to "make them be for us the body and blood of Christ".  Yet he also wants to take on board the concern of the Protestant Reformers that we can only receive Christ's presence in the Supper if we have faith.  "Make them be for us the body and blood of Christ." 

I broadly agree that an understanding that is both Biblical and informed by universal tradition should include both of these concerns.
