[X] Catholic – Excellent! Praise be to Jesus! You see sir, a good majority of the nobles and most of the populus believe in the Virgin Mary and every good Catholic can expect to be well received. This is due to king Sigismund III, who used to be called the "Jesuit King" and his long, 40 year old rule. Anyone wishing to have a career in his court or even in the provinces, had to be a Catholic or convert. Sure, some powerful men could resist this, but converting was usually easier for the sake of political expediency.
[X] Atheist – Well, this is… awkward to say the least. Sure, many people don't have much faith in anything, but they usually have a general idea, that a God does exist… somewhere. Know this: don't tell anyone. Atheism is seen as a stain on one's honour no matter where you go. Even if others might agree with you in private, they'll condemn you in public just like everybody else. Some say, that this is the only confession not covered by the Warsaw Confederation, the document guaranteeing religious freedom. So, if you're unlucky, you can end up like that French maiden, Joanne d'Arc and be burned at the stake.
