The οικια Reference in Job 1.10 and Household Baptisms

I have been posting quite a bit on baptism issues lately (see posts on Acts 16:34 and 2:41), and I’m not really sure why.  I guess I think about the issue while I’m reading the sources and I make a note to come back to certain texts for further reflection.  When I was reading Job 1 a couple weeks ago, the reference to Job and his house struck me because I remembered Lee Irons’ post on this matter here.  Irons is a more acute theologian than I, but he is convinced by Jeremias’ argument that oikos texts in the Septuagint “refer to the immediate family unit, with particular focus on the under-age children.”  Now, one is struck by the impressive list of references, which Irons compiles in his paper; however, what if it can be shown in one clear instance that the oikos formula refers to a household which has no infants in the house?  Would not that reference cause someone to pause before concluding (assuming?) there are infants in every household text in the NT?  Well, that one reference is Job 1:10.  I first commented on this issue on Weedon’s blog, which is another thread worth reviewing, if one is interested in the matter of baptism from a church history perspective.
