What is "christadelphians"

The Christadelphians (krɪstədelfiːəns) are a millenarian Christian group who hold a view of Biblical Unitarianism. There are approximately 50,000 Christadelphians in around 120 countries. The movement developed in the United Kingdom and North America in the 19th century around the teachings of John Thomas, who coined the name Christadelphian from the Greek for "Brethren in Christ".

Basing their beliefs solely on the Bible, Christadelphians differ from mainstream Christianity in a number of doctrinal areas. For example, they reject the Trinity and the immortality of the soul, believing these to be corruptions of original Christian teaching. They were initially found predominantly in the developed English-speaking world, but expanded in developing countries after the Second World War. Congregations are traditionally referred to as 'ecclesias' and would not use the word 'church' due to its association with mainstream Christianity, although today it is more acceptable.
