Well Jesus is not just any man so that is not a very good comparison.  Jesus is the ONLY begotten son of God so his wisdom is perfect because he is thoroughly perfect.  

I do believe celibate people can have great wisdom, even on sexual love, but only if they want to learn about that subject from a variety of sources and not just from a rule book of patriarchs.  

As I said elsewhere in this comment thread - Jesus did not condone any kind of break of marriage, in the Gospels, including annulments.  So our Church is not following Christ's teachings on divorce anyway.  Jesus also did not desire to keep the woman at the well who had five husbands and was living with someone who was not a husband from life giving water so why should we believe Jesus would want to keep her from life giving communion?  

We are talking apples and oranges.  Divorce is a sin as it breaks a spiritual contract and often causes adultery later on.  Eucharist was not designed to be a tool for punishment by Jesus.
