All of us, therefore, conservatives and progressives and moderates, should together take to heart what Saint Paul says to us in today’s first reading (Ephesians 4:1-7, 11-13):
I, then, a prisoner for the Lord,
urge you to live
in a manner worthy of the call you have received,
with all humility
bearing with one another
to preserve the unity of the Spirit
through the bond of peace:
and one Spirit,
as you were also called
to the one hope of your call;
and Father of all,
who is over all
and through all
and in all.
