Despite its early instillation in Jackson, the church did not grow quickly and it did not boast significant membership until the 20th century. What growth did occur after the turn of the 20th century was largely due to mergers with other congregations. In 1918, the local German Lutheran Congregation merged with the Presbyterian congregation. In 1932, the local Welsh-Presbyterians merged with the First Presbyterian Church, and the congregation swelled to nearly six hundred members. In 1941, the church received the pipe organ that is still played during every Sunday service
The Presbyterian Church originated in the 16th century from the Protestant teachings of John Calvin. The same doctrine established by Calvin formed the bases of the Anglican Church and Puritan congregationalism. The Puritans themselves were a radical offshoot of the Anglican church who believed that the church of England retained too many Roman Catholic influences and had to be purified so that the true religion could be taught. The name Presbyterian was derived from the church government structure. The Presbyterian structure is a system of government by representative assemblies called presbyteries. Structurally Presbyterianism is an alternative to Episcopal andCongregationalistt church systems. An Episcopal church system is one lead by bishops such as in the Catholic church, Lutheran Church, and Anglican church. Congregationalism is a system in which the church is run by the collective church members such as was advocated by the Puritans and is employed by Baptist and Pentecostal churches.
