The New Zealand Anglican Lectionary gives one of the titles for today to be “Proper 2”. There is no explanation, nor introduction.
Reader further: Improper Sundays
Unfortunately and inexplicably the NZ Anglican Church’s website has (a sixth of the way through the Church Year) still not placed the current PDF of its published Lectionary online – so non-Kiwi visitors to this site will need to use their imagination 🙁
