The talking donkey is Balaam's (in Numbers 22). What gets me about that is that he doesn't seem remotely surprised his donkey starts talking to him..... just answers back as if it's the most normal thing. 
As to churches opinions varying so much bearing in mind they all use the Bible, yes, it comes down to interpretations. There are those who thing the Bible is THE word of God - straight from God's mouth - 'God breathed', without error or contradiction, unchanging, and all aspects of it are relevant today - to quote the good book itself :
"All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work."
And so if the Bible says women musn't teach men, they won't allow women priests. If the Bible says women must submit to their husbands, that's what happens. If the Bible says you mustn't divorce - even in an abusive relationship, then you don't divorce. And so on.
Other churches / denominations take a different view and have allowed women vicars / priests, and realise that women can be equal to men in terms of roles, and that in some circumstances divorce might actually be the best thing for the family, etc.,
You can find websites / organisation / books etc to back up all of these viewpoints, and many of the issues have long been argued over, and probably will be for ages to come!
