I and only I am solely responsible for the following, which I report as a reminder of the importance of not taking everything at face value and of checking and re-checking information.
Looking up my lectionary in my Parson's Pocket Book (an English sourced annual diary-cum-note-taking-cum-lectionary-resource) I came up with readings for yesterday's sermon at a church which had graciously invited me. (Relevant explanation: I chose to go with the 'ordinary' readings rather than the 'extraordinary' = Presentation of Jesus readings).
Error #1: I accepted that the lectionary is the same the world over and looked forward to preaching on John 2:1-11. But it turned out (through conversation with a colleague who has a different diary but also with English based lectionary readings) that John 2:1-11 is not the reading set down in our NZ Lectionary (i.e. Matthew 5:1-12). It further turns out, as Bosco Peters' confirms, that nowhere else in the world has this particular C of E reading!! OK. I preceded to prepare a message with good content.
Error #2: when it came time for the OT reading I noticed that the reading was from 1 Kings 7:8-16. The reading should have been 1 Kings 17:8-16. But, you guessed it, on checking my emails, it was me who had sent 1 Kings 7:8-16. No, double-checking then, on my part. (Further, to make matters worse, after discovering the discrepancy between 1 John 2:1-11 and Matthew 5:1-12, I had confirmed that the readings were to be as I had sent them.) Fortunately I was able, impromptu, to make something of the 1 Kings 7 reading in relation to my 'main text', John 2:1-11.
I have learned some lessons this weekend!
