I was just reading the valid marriages thread and it got me thinking. I'm not really familiar with the rules or aspects of defecting; I don't believe I was ever taught about it, and honestly I've never even thought about it, or the implications. but this quote, from agape, got me wondering:
"Once a Catholic, always a Catholic. It is impossible to be "undone". Whether a person practices or even denies their Catholic faith, they will always be Catholic. A Catholic is bound to the promises made at Baptism "
If once you're baptised you're 100% Catholic regardless of any other behaviors or choices, then why, when joining the church as an adult do you have to complete all three sacraments of initiation? I was kind of under the impression that you weren't a full-blown adult Catholic until you were confirmed; and that basically you could walk away before confirmation scott free if you decided you didn't want to be a Catholic?
Also, if being baptised is all it takes to be a recognised Catholic then did we have to prove, in addition to baptism and confirmation, that we were active members of a parish before we could be married in the church?
Sorry if this is coming across as really uneducated. I was born and raised Catholic, but have found that I'm really not THAT informed about the subtleties of cannon law, etc.
