So after a long time thinking, I've decided I no longer desire to be Catholic. I want to let my parents know this, but I'm not sure how to go about it. They're usually rather understanding toward me, but I'm still nervous about telling them this particular decision.
Anyone have tips on how I can go about this?
How much do you not want to be a Catholic?
Technically, the only way for you to not be a Catholic would be for you to get Excommunicated from the Church, but that is usually only reserved for very serious transgressions against God and Humanity.
An alternative is just to let your faith lapse, i.e. become a Lapsed Catholic. You'll still technically be a Catholic in the eye of the Church, as a lapse in faith doesn't undo your Baptism and Conformation, but you won't be obligated to attend Mass or follow the Faith (although you can still choose to identify as a Catholic if you so desire, and attend Mass with your family on special occasions like Christmas and Easter).
It may be easier on you and your parents if you become a Lapsed Catholic, rather than stating that you 100% believe that you don't believe in a God and reject your parents faith and beliefs.
Unless Atheism is as important to you as the Church is to Catholics, in that you're practically swapping one religion or set of beliefs for another, it may be a lot easier on everyone involved if you just let your faith lapse.
