Bless the bread and the wine

It's surprising what you read, sometimes.

That arch-Reformed Protestant document, The Westminster Confession of Faith, says that:

The Lord Jesus hath, in this ordinance, appointed his ministers ... to pray, and bless the elements of bread and wine, and thereby to set them apart from a common to a holy use;

(Chapter 29, Paragraph 3)

I imagine many contemporary evangelicals would be less fussed about the need for a minister or a prayer of consecration.
