Jesus said, ‘From the beginning of creation, “God made them male and female.” “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.’
People were bringing little children to him in order that he might touch them; and the disciples spoke sternly to them. But when Jesus saw this, he was indignant and said to them, ‘Let the little children come to me; do not stop them; for it is to such as these that the kingdom of God belongs. Truly I tell you, whoever does not receive the kingdom of God as a little child will never enter it.’ And he took them up in his arms, laid his hands on them, and blessed them.
