Executive summary

Colonial laws and the first state constitutions (1776–1800) repeatedly treated religion—mostly Christianity—as central to public order: many colonies maintained established churches, mandated worship or taxes for ministers, and required religious tests or oaths for officeholders [1] [2] [3]. At the state-constitution level after 1776 there was wide variation: some documents declared that government depended on “piety, religion and morality” (Massachusetts) or preserved laws supporting Christianity (Maryland), while others moved toward disestablishment and legal toleration for different Christian sects [4] [3] [5].

1. State houses that read like pulpits: formal endorsements of Christianity

Many colonial governments and later state constitutions kept formal ties to Christianity. Eight of the thirteen colonies had an “established” church and laws that funded ministers or mandated worship; courts and legislatures often referenced scripture in criminal statutes or local law codes [1] [6] [2]. After independence, state documents sometimes echoed this view: the Massachusetts Constitution declared civil order dependent on “piety, religion and morality,” and other states authorized taxes or public support for Christian worship [4] [3].

2. A spectrum from establishment to toleration, not a single model

The era produced multiple, competing approaches. Some states continued established churches and required religious tests or public support for ministers; others extended legal toleration to all Christian sects while still excluding non-Christians from office or imposing Christian oaths [3] [7]. A handful—most famously Rhode Island and Pennsylvania earlier—offered broader pluralism, but even these often assumed Christianity shaped public life [8] [2].

3. Tests, oaths and limits on office-holding

Religious tests and oaths were common in early state constitutions and statutes. Many states initially required officeholders to profess belief in God or Christianity; some retained these requirements well into the 19th century [7] [3]. At the federal level the Constitution’s Article VI forbade religious tests for federal office (a notable break), and several states responded by loosening or removing their own tests in the 1790s [9] [7].

4. Founders and conflicting philosophies: civil religion vs. Enlightenment pluralism

Leading figures and state documents reflected a tension: a tradition that saw law as building a “Christian polity” and citing scripture (especially in New England), versus Enlightenment-influenced calls for conscience and disestablishment [10] [6]. Virginia’s debates—Jefferson’s Statute for Religious Freedom and Madison’s Memorial and Remonstrance—illustrate that struggle; Virginia moved toward protecting individual conscience while other states retained public support for Christianity [11] [7].

5. Practical consequences: what citizens actually experienced

Laws mattered. In places with established churches, taxes supported ministers, dissenters faced civic penalties, and local legal codes sometimes enforced religious observance [1] [2] [12]. Some states explicitly preserved penalties for blasphemy or protected Christian worship in fundamental law [13]. Conversely, other jurisdictions allowed incorporation of multiple denominations or abolished formal denominational preference, producing local variations in day-to-day religious freedom [14] [5].

6. The federal framing changed the incentives but not immediate state practice

The 1791 Bill of Rights barred establishment at the national level and protected free exercise, but it did not automatically override state constitutions; state establishments and religious tests persisted into the 19th century and required separate political and legal battles to end [5] [15] [14]. Legal scholarship and primary-document collections show states gradually removed established-church mechanisms and religious tests over decades following the Revolution [9] [7].

7. What the sources agree on — and what they dispute

Primary and secondary sources converge on three facts: Christianity dominated colonial legal culture; many states initially kept elements of establishment after 1776; and the Constitution and Bill of Rights introduced a competing federal norm against national establishment [1] [2] [15]. Scholars disagree on pace and motive: some emphasize an Enlightenment-driven move toward religious liberty, others stress continuity of Christian civil religion and slow disestablishment [10] [5].

Limitations: available sources here summarize broad patterns and notable examples (Massachusetts, Maryland, Virginia, Pennsylvania) but do not list every state clause verbatim; for state-by-state constitutional texts or precise wording, consult the primary constitutions and the detailed JSTOR study cited [16].
