Holy Gospel of Jesus Christ according to Saint Matthew 10:34-42.11:1
Jesus said to his Apostles: “Do not think that I have come to bring peace upon the earth. I have come to bring not peace but the sword.
For I have come to set a man ‘against his father, a daughter against her mother, and a daughter-in-law against her mother-in-law; and one’s enemies will be those of his household.’ Whoever loves father or mother more than me is not worthy of me, and whoever loves son or daughter more than me is not worthy of me; and whoever does not take up his cross and follow after me is not worthy of me. Whoever finds his life will lose it, and whoever loses his life for my sake will find it. Whoever receives you receives me, and whoever receives me receives the one who sent me.
Whoever receives a prophet because he is a prophet will receive a prophet’s reward, and whoever receives a righteous man because he is righteous will receive a righteous man’s reward.
And whoever gives only a cup of cold water to one of these little ones to drink because he is a disciple–amen, I say to you, he will surely not lose his reward.”
When Jesus finished giving these commands to his twelve disciples, he went away from that place to teach and to preach in their towns.

“He who welcomes you welcomes me”
The Lord said: “Whoever welcomes this little child on my account welcomes me.” (Lk 9:48) The smaller our brother is, the more Christ is present. For when we welcome a great personality, we often do so out of vainglory; but the person who welcomes someone unimportant, does so with a pure intention and for Christ. He said: “I was a stranger and you welcomed me.” And again: “As often as you did it for one of my least brothers, you did it for me.” (Mt 25:35.40) Since he is talking about a believer and a brother, no matter how unimportant he is, Christ comes in with him. Open your house and welcome him.
“He who welcomes a prophet because he bears the name of prophet receives a prophet’s reward.” Thus, the person who welcomes Christ will receive the reward of Christ’s hospitality. Do not doubt his words, trust them. He himself told us: “In them, I am presenting myself.” And so that you do not doubt them, he decreed the punishment for those who do not welcome him and the honors for those who do welcome him (Mt 25:31ff.). He would not do this if he were not personally touched by honor or scorn. He says: “You welcomed me into your house; I will welcome you in the Kingdom of my Father. You freed me from hunger; I will free you from your sins. You saw me in chains; I will let you see your liberation. You saw me a stranger; I will make of you a citizen of heaven. You gave me bread; I will give you the Kingdom as your inheritance that is entirely yours. You helped me in secret; I will proclaim it publicly and I will say that you are my benefactor and that I am in your debt.”
