ART. III. As the public worship of GOD and instructions in piety, religion and morality, promote the happiness and prosperity of a people and the security of a republican government;--therefore, the several religious societies of this commonwealth, whether corporate or unincorporate, at any meeting legally warned and holden for that purpose, shall ever have the right to elect their pastors or religious teachers, to contract with them for their support, to raise money for erecting and repairing houses for public worship, for the maintenance of religious instruction, and for the payment of necessary expenses: and all persons belonging to any religious society shall be taken and held to be members, until they shall file with the clerk of such society, a written notice, declaring the dissolution of their membership, and thenceforth shall not be liable for any grant or contract which may be thereafter made, or entered into by such society:--and all religious sects and denominations, demeaning themselves peaceably, and as good citizens of the commonwealth, shall be equally under the protection of the law; and no subordination of any one sect or denomination to another shall ever be established by law.
