“We establish no religion in this country, we command no worship, we mandate no belief, nor will we ever. Church and state are, and must remain, separate. All are free to believe or not believe, all are free to practice a faith or not, and those who believe are free, and should be free, to speak of and act on their belief. At the same time that our Constitution prohibits state establishment of religion, it protects the free exercise of all religions. And walking this fine line requires government to be strictly neutral.” —Ronald Reagan
I found this quote at Reddit, and it’s attributed to a speech dated August 23, 1984 at an ecumenical prayer breakfast in Dallas, Texas. Can anyone else confirm this?

This website seems to agree:
