Presbyterian end of things, the following is the precis of a message preached on the "Free" of Free Presbyterian:
Because we uphold the doctrines and practices of Presbyterianism, we looked briefly at the origins of our denomination. Being convinced of the rampant apostasy of the Presbyterian Church in Ireland, a group of men in 1951 decided against the relatively useless tactic of "staying in to fight" and obeyed God and separated from the apostate body (2 Corinthians 6:14-18/Ephesians 5:11 etc.)
We are Free Presbyterian because:
A/ WE ARE FREE FROM MODERNISM:
We uphold and preach and contend for the fundamentals of the Christian faith - which we listed - and actively and aggressively oppose modernism especially that represented by Professor J.E. Davey who was acquitted in the famous 1926 Heresy Trial in the Presbyterian Church in Ireland. Professor Davey shamelessly denied the Virgin Birth, attacked the Westminster Confession of Faith (although he swore before God and men at his ordination to uphold it ) and some of the major Christian doctrines e.g. the blood atonement of Jesus Christ and admitted to Unitarianism.
A modernist would not be tolerated in the FPC (Titus 3:10) never mind elevated to the Moderator's chair as Davey later was in his denomination.
B/ WE ARE FREE FROM ECUMENISM:
I gave the proper interpretation of the prayer of the Lord Jesus in John 17 which has been hi jacked by the ecumenists.
The Presbyterian Church of Ireland were heavily involved in the World Council of Churches - although they left direct membership, yet they are still in membership of associate bodies (i.e. nothing has substantially changed).
The FPC actively opposes the co-operative ecumenical evangelism of the likes of Billy Graham who sends his converts back into the Church of Rome (Matthew 23:15)
C/ WE ARE FREE FROM WORLDLINESS:
Admittedly, this is the hardest thing to be free from!
Every FPC minister at his ordination vows to oppose "the social vices of: drinking, gambling and dancing" The Church does not approve of smoking and worldly attire which, among other things, breaks down the God given distinctions between modesty and immodesty.
The above is only a brief outline of a sermon. More information on the FPC available here
