This was over the issued of subscription to the Westminster Confession of Faith. Those who denied the necessity of subscribing to the Confession were known as New Light Presbyterians. In 1725 for the sake of convenience those who took this stance were placed in the Presbytery of Antrim. Other brands of Presbyterianism originating in Scotland were established in Ulster during the course of the eighteenth century.
The Seceders as they were known, because they had seceded from the Church of Scotland in 1733, soon established congregations and presbyteries in Ulster. The first Irish presbytery of the Reformed Presbyterian Church was established. The origins of this denomination went back to the National Covenant of 1638 and the Solemn League and Covenant of 1643.
The Reformed Presbyterians, or Covenanters as they were also known, refused to accept that the state had any authority over the church and did not participate in parliamentary elections. Both of these denominations provided an alternative to mainstream Presbyterianism.
