Maryland Assembly Passes Toleration Act
In a colony founded as a Catholic refuge amid England's religious conflicts, the Maryland Assembly enacted one of North America's earliest laws protecting worship for multiple Christian groups.
Summary
Lord Baltimore, proprietor of the Maryland colony founded as a refuge for English Catholics, faced growing Protestant influence and the disruptions of the English Civil War. To protect Catholic settlers and attract Puritan migrants while maintaining stability, he directed the colonial assembly to enact legal safeguards. On April 21, 1649, the assembly in St. Mary's City passed the Act Concerning Religion, also known as the Maryland Toleration Act. The law granted freedom of worship to all Trinitarian Christians and imposed penalties for religious insults or persecution. It represented one of the earliest colonial statutes explicitly protecting religious liberty for multiple Christian denominations in North America.
Context
The Province of Maryland originated from the vision of George Calvert, who secured a charter from King Charles I in 1632, and his son Cecil Calvert, who implemented it after George's death. The Calverts, English Catholics facing persecution at home, intended the colony both as a sanctuary for coreligionists and a commercial venture. Early settlers included Catholics and Protestants, with instructions from the proprietors emphasizing peace between the faiths and private practice of Catholicism to avoid friction.
By the late 1640s, the English Civil War had intensified divisions across the Atlantic, with royalist and parliamentary factions influencing colonial loyalties. Protestant settlers, including Anglicans and arriving Puritans, soon outnumbered the initial Catholic population in Maryland. Cecil Calvert, seeking to stabilize the colony and fulfill promises of worship rights made to attract new migrants, directed the assembly to formalize protections.
The resulting legislation addressed vulnerabilities exposed when Protestants briefly seized control after Governor Leonard Calvert's death in 1647. It reflected practical governance rather than abstract principle, aiming to prevent religious strife from undermining proprietary authority.
What Happened
On April 21, 1649, the colonial assembly convened in St. Mary's City and passed the Act Concerning Religion. The measure extended freedom of worship to all who professed belief in the Trinity and the divinity of Jesus Christ, while prohibiting the use of religious epithets or insults against Trinitarian Christians. It imposed fines, whipping, or imprisonment for violations and the death penalty or property forfeiture for denying core Christian doctrines.
Cecil Calvert had prompted the assembly's action partly to honor assurances given to a group of Puritans invited to settle at what became Providence. The law applied equally to Catholics, Anglicans, and Puritans, marking a deliberate effort by the Catholic proprietor to secure the rights of a Protestant majority.
Assembly members, many of them Protestant, approved the statute under the proprietary government's direction, embedding specific penalties to deter persecution while limiting its scope strictly to Trinitarian believers.
Aftermath
The act remained in force only briefly. In 1654, following Parliament's victory in England and the appointment of Protestant commissioners including William Claiborne, the assembly repealed the law and barred open Catholic worship. Cecil Calvert regained control through negotiation, leading to the act's restoration by 1657.
Further upheaval came after the Glorious Revolution, when Maryland Protestants overthrew proprietary rule in 1689, permanently repealing the toleration provisions and establishing the Church of England as the official faith.
Legacy
The Maryland Toleration Act stands as the first colonial statute in British North America to guarantee religious liberty, albeit limited, to multiple Christian denominations. Its phrasing on the "free exercise" of religion later echoed in the First Amendment.
Historians note its role as a pragmatic response to demographic shifts and political instability rather than a broad endorsement of pluralism. Though repealed and never fully restored under colonial rule, it influenced subsequent toleration measures in other colonies and served as an early precedent cited in American debates over conscience and worship.
Why It Matters
The act pioneered statutory religious tolerance in the English colonies, influencing later American concepts of freedom of conscience and serving as a model cited in debates leading to the First Amendment, despite its later repeal and restoration.
