Question 6: Can we get married without there being a Mass? -

Yes. Talk to the priest and you might be advised also to talk to some friends and family before you make this decision. The decision you come to may depend on various factors: such as your marriage being an inter-faith marriage (and the likelihood or otherwise of the Mass being seen as emphasising division rather than unity), or such as one of the partners to your marriage having chosen to cease Church practice, or such as the majority of your guests being unlikely to be persons of faith.
