Technically, but it depends on how you define that. For instance "Vatican City" is a country, and their one religion is Catholicism. Some countries have "state religions" like Iran has Islam as its toted religion.
Most countries have a variety of beliefs though.
Roman State religion was idolatrous and Christianity believes in the one true God.
If they are mixed their will not be freedom of religion because the one which selcted as state religion will put great presure on the other religion.We can take a good example from ethiopian history
No, Australia does not have an official "state religion", but the country was founded on Christianity. One of the provisions in Australia's constitution is the guarantee of freedom of religion for all, so many religions are now represented.
The USA has no state religion but most of the country worships Jesus in one way, shape or form.
Today's interpretation of "separation of church and state" implies that religion of any kind cannot be involved in any governmental entity, ceremony, or action. This implies that one's religion must be limited in the life of an individual. In that sense, "freedom of religion" - that is to say, the freedom to exercise one's religion over the lives of others - is hindered.
No state has an official religion.
There are many people in Manitoba practicing many different religions. There is not one official state religion in Manitoba or elsewhere in Canada.
If there was a relation between state power and religion, there would be widespread legal persecution of those who are not of the "correct" religion. To escape religious persecution was one of the reasons America was created.
Catholicism is the state religion.
It did not have an Official State religion.
Islam is the state religion
One of the great attributes of the United States of America is that we (technically) have no state religion; There fore, you are free to practice any religion you wish as long as it doesn't conflict with state and federal law. I mentioned a technicality before, while we have no state religion a vast majority of the population practices Christianity.
