Service of the kingdom

Part of the following passage is reflected in Anglican and other wedding rites.  But perhaps the last paragraph is the most interesting from my perspective.  

In ancient cultures, some of the most precious jobs were given to those who had been physically incapacitated.  These jobs included looking after the king's harem.  

But here it just seems a bit out of place... the disciples say "if marriage is hard to get out of, don't get married" then Jesus says well some people are Eunuchs for the kingdom... 

Here it seems that Jesus points out the sharp edge of the bible's teaching on human sexuality.  Married for life, or not at all.  No easy way out here.  But some people, including some of the disciples who for the service of Christ have to travel far and wide unencumbered by a wife, it would seem the Eunuchs who have made themselves Eunuchs for the kingdom of heaven are doing a good thing for all involved.

I guess here there are two key bits here... they make themselves Eunuchs... and they do it for the kingdom.

Now when Jesus had finished these sayings, he went away from Galilee and entered the region of Judea beyond the Jordan. And large crowds followed him, and he healed them there.  And Pharisees came up to him and tested him by asking, "Is it lawful to divorce one’s wife for any cause?" He answered, "Have you not read that he who created them from the beginning made them male and female, and said, 'Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh'? So they are no longer two but one flesh.  What therefore God has joined together, let not man separate."  They said to him, "Why then did Moses command one to give a certificate of divorce and to send her away?" He said to them, "Because of your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery."

The disciples said to him, "If such is the case of a man with his wife, it is better not to marry."  But he said to them, "Not everyone can receive this saying, but only those to whom it is given. For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let the one who is able to receive this receive it."

(Matthew 19:1-12 English Standard Version)

Oh and by the way, it is also bookended by a quote picked up in the Anglican Infant Baptism liturgy about young children.
