"I thought about it.
If they make the law for the believers, that is, add them rights, then let us add the duties and official registration of the believers?
Do you want your rights to be protected?
Register, pray in the morning and evening, observe fasting, etc.
And yes, the exam for knowledge of sacred texts."

I fully support it as a believer. In today’s world, there is nothing shameful or dangerous about attributing yourself to a religion. This may help many to decide. And for those who find it difficult, it will be useful to read what they believe.
The exam for knowledge of sacred texts still exists in some dioceses, say, for the baptized.

Only, there is a constitutional right that a person is not obliged to report his religious opinions to anyone. This will hinder your idea. and :)
