Freedom of Religion

What is the oldest written source in this country that mentions this right?

Finland

The Finnish Constitution Act of 1919 stipulated that “a Finnish citizen has the right to practice religion publicly and privately, provided that the law and good practices are not violated, as well as, as separately provided thereon, the freedom to renounce the religious community to which he belongs and the freedom to join another religious community.” This assurance is found under Section 8 and applies to all citizens of Finland (“Constitution Act” 1919). Under the 2000 Constitution of Finland sections 6 and 11 grant religious freedom, equality, and prohibit religious discrimination.
