Reformed churches are predominantly Presbyterian in polity, where the congregation is governed by a group of elected elders who are lay persons and a minister. Regional groups of churches form a Presbytery, and groups of Presbyteries form Synods that together form the national General Assembly. The Reformed Tradition is monotheistic, affirming one God, in three persons. The persons of the Trinity are God the Father, God the Son, and God the Holy Spirit. Reformed Christians are called, always and everywhere, to a committed pursuit of social justice and human wholeness. Disease, illness, suffering, and death, and indeed natural disaster as well, are a consequence of humankind’s choosing to go its own way and to live. Theologically, death is a consequence of human willfulness or going our own way in disobedience to God. Reformed Christian religious terminology reflects, in large part that found in mainstream Protestant Christian traditions.
