While the testimony of the Free Presbyterian Church of Scotland coincides with the whole doctrine of the Westminster Confession, certain issues are particularly important:

1. The verbal inspiration of scripture
   We reject all theories of partial inspiration. We maintain that the Bible is the Word of God, inspired and infallible, from beginning to end.
2. The Trinity
   We believe that God exists in three Persons: Father, Son, and Holy Spirit.
3. The person of Christ
   We believe in the divinity of Christ, in the virgin birth and in His resurrection.
4. The atonement
   We believe that Christ died for the elect only, and we are opposed to the doctrine of universal redemption, as also salvation by man's good deeds. We stress the sovereignty of God in salvation, but we also emphasise man's responsibility. Hence, in line with Scripture, we proclaim Christ crucified for sinners, "that whosoever believeth on Him should not perish but have everlasting life" (John 3:16).
5. The headship of Christ
   We believe that Christ is the sole Head of the Church and has appointed Church officers to administer its affairs, distinct from the civil government. These officers have a spiritual jurisdiction, co-ordinate with, and not subordinate to, the civil jurisdiction of the civil magistrate. But further, we hold that Christ is not only King of saints, but also King of nations, "Lord of lords and King of kings" (see Jeremiah 10:7; Psalm 2; Revelation 17:14, etc), and that the State, as such, is under obligation to acknowledge and support His cause and truth. We believe in what is called the Establishment Principle.
6. Purity of worship
   We oppose the use of instrumental music in the public services of God's house, and at the same time maintain that the Book of Psalms is the divinely appointed manual of praise in the worship of God. Consequently, we do not use uninspired hymns or Paraphrases in our worship.
7. The Sabbath
   We believe that God requires us to keep the Lord's Day as the Christian Sabbath.
8. Baptism
   We believe that the children of believers should be baptised and that baptism is correctly administered by sprinkling or pouring.
9. The exercise of a firm discipline, in the spirit of the gospel
   This discipline is not lordly but ministerial; it is delegated by Christ to those who rule in the Church (Hebrews 13:7, 17). To dispense with discipline is to dispense ultimately with the Gospel. Without it the purity of the Church is jeopardised.
10. Others
    1. We believe that the Authorised Version of the Bible should be used in public worship.
    2. We reject the observance of Christmas and Easter and other church festivals as unbiblical
    3. Pentecostalism - we believe that the extraordinary gifts of the Holy Spirit given to the early New Testament Church have ceased.
    4. Headcovering in public worship - we believe that the Bible requires women to cover their heads in public worship.
    5. We believe that we should stand for Prayer in public worship.

All the above points have their basis in Scripture, and are enunciated in the Westminster Confession of Faith.
