All the readings for Sunday Mass are here.
This is the second reading from Galatians 3 : 26-29 and is one of my favourites.
Brothers and sisters:
Through faith you are all children of God in Christ Jesus.
For all of you who were baptized into Christ
have clothed yourselves with Christ.
There is neither Jew nor Greek,
there is neither slave nor free person,
there is not male and female;
for you are all one in Christ Jesus.
And if you belong to Christ,
then you are Abraham’s descendant,
heirs according to the promise.
Jesus Christ didn't seem to be bothered about the issues we spend so much time wrangling about - the mission was the important part.
