One of the more bizarre changes to the calendar in 1970, surely designed only to confuse, was the change in the numbering system of Sundays in certain seasons of the year. The net result is that while in the Extraordinary Form, this Sunday is the Second Sunday after Easter, in the Ordinary Form it is the Third Sunday of Easter. Go figure!
Naturally, the Gospels no longer align either - in the EF it is Good Shepherd Sunday (John 10: 11-16); in the OF, the text is John 21:1-19.
That's a shame it seems to me. Whatever the merits of new lectionary's use of more of Scripture, there are certain texts, reflected in the Churches ancient Sunday Gospel cycle, that every Catholic ought to know more or less by heart, and repeating them every year helps ensure that. But alas, in the Novus Ordo lectionary, this beautiful and important text comes around only once every three years, and you had your chance last year!
