Blessing or Grace?

Welcome to the first posting. I am hoping to establish some opportunity for discussion about issues that arise from my own double life as local church minister and university teacher.

Looking around a couple of other Baptist blogs there seems to be some discussion going on around whether to use a blessing or say the grace at the end of a service. Geoff Colmer (geoffcolmer.blogspot.com/) argues for the importance of a blessing, especialy one of the biblical texts. Steve Holmes (shoredfragments.wordpress.com/) asks whether we say 'we' or 'you' when preaching or pronouncing the blessing. As for me, I think I do both. As preachers and ministers we proclaim the authoritative word of God, but we are all under that authority. I tend not to use the grace so much these days simply because it is widely unknown by visitors (though data projection can overcome this). Some questions arise. How do we understand our role as 'priestly' but not as 'priest?' Can we hold to some form of sacramentality of ministry whicle remaining under the authority of the Word and the gathered congregation? Whatever the answers, it's good to be blessed anyway!
