1. Why can't Catholic girls use birth control even if it's not being used for having sex (such as, managing their menstrual cycle)?

2. Where does anger come from? And if it's from the devil why did Jesus get angry in the temple (when they turned it in to a market)?

3. Can I go to a wedding of someone that I know is going against the church teachings in their relationship? Or would that be congratulating them for living in sin?
