From the Gospel according to Luke 9:46-50
An argument arose among the disciples
about which of them was the greatest.
Jesus realized the intention of their hearts and took a child
and placed it by his side and said to them,
"Whoever receives this child in my name receives me,
and whoever receives me receives the one who sent me.
For the one who is least among all of you
is the one who is the greatest."
Then John said in reply,
"Master, we saw someone casting out demons in your name
and we tried to prevent him
because he does not follow in our company."
Jesus said to him,
"Do not prevent him, for whoever is not against you is for you."
The Gospel of the Lord.
Praise to you, Lord Jesus Christ.
