Let me just preface this post by saying that I'm not a lawyer, altough I do have law school training (took the notary track).
If you look at the federal provisions, you see that the brewing of beer is permitted for personal or family use if it not in contradiction to state or local law.
If you look at the dispositions on removal of beer you see:
§ 25.206 Removal of beer.
Beer made under §25.205 may be removed from the premises where made for personal or family use including use at organized affairs, exhibitions or competitions such as homemaker's contests, tastings or judging. Beer removed under this section may not be sold or offered for sale.
This seems to indicate to me that personal and family use should be interpreted in a inclusive fashion, since the removal of beer to be served at organized affairs (such as a wedding) is permitted under federal law. Unless you apply some ridiculous logic, it'S pretty much guaranteed that beer removed from the household to be drank at an organized affair is not going to be only for the guy who produced it and his family.
Now, the state statute you have quoted do not in any shape or form apply to a wedding, unless you practice some wishful thinking or voluntary blindness. A wedding is not a competition, no matter how many scoresheets you scatter around. I'd say that unless you can spot something in state or local law that prohibits serving beer at a wedding, you're fine.
This doesn't mean that such a law like this doesn't exist or that trouble could not arise from you serving your homebrew. If the venue has no permit to serve alcohol on the premises or some company has exclusivity rights to serve their product at the venue, there might be an issue. I know that up here, if you plan on having more than X people in attendance and you plan on people drinking (yes, even free stuff), you need a permit to do so.
