The Unity of God and the Rejection of the Trinity
As taught in the Christadelphian tradition
How Christadelphians confess one God, the Father, and decline the Nicene Trinity.
The Christadelphian community, which traces its modern organisation to the medical doctor and writer John Thomas in the 1840s and 1850s and to the consolidating work of Robert Roberts in the following generation, holds among its most defining and most contested convictions a strict, undivided monotheism. On this reading there is one God, the Father, a single self-existent personal Being, and the doctrine of the Trinity - one God in three coequal, coeternal persons - is regarded not as a clarification of biblical monotheism but as a departure from it. This places the tradition outside the Nicene mainstream that unites Roman Catholic, Eastern Orthodox, Oriental Orthodox, and the great body of Protestant churches, and the difference is not cosmetic: it touches the identity of God, the nature and origin of Jesus Christ, and the meaning of the Holy Spirit.
By the end of this lesson
- Explain the Christadelphian confession that God is one undivided personal Being, the Father, as set out in the Birmingham Amended Statement of Faith, and contrast it with the Nicene confession of one God in three persons.
- Describe how Christadelphians understand the Holy Spirit as God's own power 'in unity with His person' rather than a distinct third divine person, and how this differs from the creedal confession of the Spirit.
- State the Christadelphian denial of the personal pre-existence of the Son, locating Jesus' beginning at his miraculous begettal, and identify the precise point at which this diverges from the Nicene 'begotten before all worlds, of one substance with the Father.'
- Show how the four anchor passages (Deuteronomy 6:4; 1 Corinthians 8:6; John 17:3; 1 Timothy 2:5) are read together as a chain supporting biblical unitarianism, and summarise the mainstream Trinitarian rejoinder to each.
- Identify the tradition's primary sources - the Birmingham Amended Statement of Faith, John Thomas's Elpis Israel (1849), and Robert Roberts's expository work and editorship of The Christadelphian - and the distinct role of each.
- State fairly and without flattening where the Christadelphian doctrine of God differs from historic creedal Christianity on the Trinity, the deity and pre-existence of the Son, and the personhood of the Spirit, and explain the principled basis each side gives for its position.
