"[A]fter Leonard Calvert died in 1648, Lord Baltimore appointed the Protestant William Stone as governor. He required the governor to take an oath not to violate the free exercise of religion by any Christians, specifically including Roman Catholics. Subsequently, in April 1649, the Maryland Assembly passed the famous Toleration Act, which guaranteed all Christians the free exercise of their religion. However, tolerance and religious liberty went only so far and the death penalty was levied against all non-Christians, including Jews and Unitarians. Neither did toleration extend to freedom of speech, for any use of such religious epithets as "heretic" and "popish priest" was outlawed. Also prohibited on the Sabbath were swearing, drinking, unnecessary work, and disorderly recreation. Actually, the much vaunted Toleration Act was a retreat from the religious liberty that had previously prevailed in Catholic-ruled Maryland, and was a compromise with the growing spirit of Puritan intolerance."
