The entirety of this Sunday's second reading might be seen as so much boilerplate, throwaway lines that a writer used at the commencement of his letter, something like a formal salutation. But in point of fact, almost the whole of Christianity is contained in these lines, if we have but the eyes to see. So take out your Bibles today and revisit the beginning of 1 Corinthians. It will tell you pretty much everything essential that you need to know about yourself and your mission.
