Sixth Sunday of Easter, May 13, 2007

Since, in my locality, the Ascension falls on the Seventh Sunday of Easter, we are permitted to use readings of that Seventh Sunday on this day.  I used the Gospel from next Sunday: "That all may be one."  How does the incident in the Acts of the Apostles demonstrate for us the manner in which we should seek communion among all believers?  How are we preparing to enter the New Jerusalem?
