Matthew 18:1-10 New Revised Standard Version Catholic Edition (NRSVCE)
18 At that time the disciples came to Jesus and asked, “Who is the greatest in the kingdom of heaven?” 2 He called a child, whom he put among them, 3 and said, “Truly I tell you, unless you change and become like children, you will never enter the kingdom of heaven. 4 Whoever becomes humble like this child is the greatest in the kingdom of heaven. 5 Whoever welcomes one such child in my name welcomes me.
Temptations to Sin
6 “If any of you put a stumbling block before one of these little ones who believe in me, it would be better for you if a great millstone were fastened around your neck and you were drowned in the depth of the sea. 7 Woe to the world because of stumbling blocks! Occasions for stumbling are bound to come, but woe to the one by whom the stumbling block comes!
8 “If your hand or your foot causes you to stumble, cut it off and throw it away; it is better for you to enter life maimed or lame than to have two hands or two feet and to be thrown into the eternal fire. 9 And if your eye causes you to stumble, tear it out and throw it away; it is better for you to enter life with one eye than to have two eyes and to be thrown into the hell[a] of fire.
The Parable of the Lost Sheep
10 “Take care that you do not despise one of these little ones; for, I tell you, in heaven their angels continually see the face of my Father in heaven.[b]
