Holy Viaticum: perhaps we need an article on that, or at least explanation of it in this one as the phrase currently redirects here. On another matter, I'm a little concerned about this paragraph:  

 :While changes were proposed to this sacrament in the wake of the Second Vatican Council, there are actually hundreds of Catholic priests around the world who still offer the traditional form, matter, and intent of the sacrament of Extreme Unction. For a look at what the sacrament is like in its centuries-old form, watch the movie Brideshead Revisited adapted from the novel by Evelyn Waugh. 

 We need more discussion of how the form these priests offer differs from the new form. The last sentence needs replacing with a description of the centuries-old form. It's no good directing the reader to go and watch a movie to find out what it's like. If anyone knows about all this it would be good if they could add it in. —
