Plenty of people are raised Catholic and then aren't Catholic anymore, like any religion.

Religion did not exist for the saving of souls but for the preservation and welfare of society, and in all that was necessary to this end every man had to take his part, or break with the domestic and political community to which he belonged.

The dissolution of the nation destroys the national religion, and dethrones the national deity.

I don't think you need religion.

Thus a man was born into a fixed relation to certain gods as surely as he was born into a relation to his fellow-men and his religion... was simply one side of the general scheme of conduct prescribed for him by his position as a member of society.
