The General Assembly of the Presbyterian Church (USA) determines and approves ecumenical declarations, agreements and maintains correspondence with other Presbyterian and Reformed bodies, other Christian churches, alliances, councils and consortia. Ecumenical declarations and agreements are subject to ratification by the presbyteries. Here are some of the key ecumenical agreements and partnerships to be found. The agreement is based on the doctrinal consensus formulated in A Common Calling: The Witness of Our Reformation Churches in North America Today and must be considered in accordance with this document. The aim of A Formula of Agreement is to shed light on the complementarity of affirmation and exhortation as a fundamental principle of entry into the full community and on the impact of this act, as described in A Common Calling. Reformed Presbyterians have historically been called Covenanters because they have identified themselves with public alliances in Scotland since the 16th century. In response to the King`s attempts to change the style of worship and governance in churches that had been (rented) by free assemblies and Parliament, a number of ministers reaffirmed their respect for these earlier agreements by becoming signatories to the February 1638 “National Pact” at Greyfriars Kirk in Edinburgh. From there comes the Blue Banner, which proclaims “For the Crown and the Covenant of Christ,” because the Covenant saw the King`s attempt to change the Church as an attempt to claim the head of Jesus Christ. The first great awakening and the awakening effect had a great influence on the American Presbyterians.
Ministers such as William and Gilbert Tennent, a friend of George Whitefield, stressed the need for a conscious conversion experience and insisted that moral standards be higher in the clergy.  Disagreements over the awakening, walking sermons and pedagogical requirements of clerics led to a split known as the Old Side-New Side Controversy, which lasted from 1741 to 1758.  Two other seminaries are linked to the PC (USA) by agreement: the Auburn Theological Seminary in New York, New York, and the Evangelical Seminary of Puerto Rico in San Juan, Puerto Rico. In July 2010, the General Assembly voted by 373 votes to 323 in favour of amending the Presbytery Constitution for ratification to remove Chapter G-6.0106.b of the Book of order. or chastity in solitude. This proposal required ratification by the majority of the 173 presbyteries within 12 months of the general assembly adjournment.   In May 2011, a majority of Presbyterian votes were reached. The amendment to the Constitution came into force on July 10, 2011.  This change has referred to ordination the responsibility of deciding who to ordain and what they ask of their candidates for ordination.
