Is The Use Of "Donor" Gametes Biblically Permissible?

Something I see pretty frequently when people ask the question online if it's ok for Christians (or anyone for that matter) to use a sperm donor to conceive a baby is a terribly inaccurate use of Scripture to support an affirmative answer.  "Go forth and multiply!" and "Children are a blessing from the Lord!" seem to be the standard fare as an answer.  Those two verses are taken completely out of context when given as a prescriptive answer in this situation.  Context is so important to knowing what a verse actually says and means.*

So I'm trying to figure it out - just where does God stand on this issue of introducing a third party into the one-flesh relationship of marriage?  My feeling is that it is not a "God sanctioned" way to create a child, however I know my feelings are no basis for truth since feelings change and truth does not, by it's very definition.  I do not feel that it is on the same level as adultry since there is no physical relationship involved in the use of a donor (at least in mainstream cases...I guess there's always the exception to the rule.)  But I just don't see God giving loopholes in marriage: ie., my spouse can't give me a child, so I'll get someone else to give me a child.  And doesn't it seem akward to know that a wife is having another man's baby?  Is God cool with that?

I am praying for wisdom.



*There is a story about the man who decided to seek guidance from God by opening the Bible at random and sticking a pin in the page, and trusting that the words where the pin stuck indicated God's will for him.

The pin landed in the latter part of Matthew 27:5, describing the actions of Judas Iscariot: "he went and hanged himself."

Not satisfied with the result, the man tried again, and this time the pin landed at the end of Luke 10:37: "You go, and do likewise."
