As many know, I have an interest in the Christadelphian movement, and have read/written much about and against it. I did come across the following discussion of a 16th-century Anabaptist/Unitarian group that, like Christadelphians, did not believe everyone would be raised to judgment, rejected a personal devil, and held to a Socinian model of Christology:
In 1550 an Anabaptist/Unitarian synod was held at Venice,
with about sixty delegates attending. Questions pertaining to the Trinity and
the person of Christ were the matters of foremost concern, and the body issued a
statement of ten points to clarify its teaching. The following summary of that
statement shows the character of the Italian Brethren faith.
1. Christ is not God but the son of Joseph and Mary, one
filled with divine powers;
2. Mary bore additional children after
Jesus;
3. Angels are merely men commissioned by
God for special tasks;
4. There is no personal devil;
5. The final resurrection will not
include the unrighteous; they will remain in the grave forever;
6. The grave is the only hell;
7. The righteous sleep until the last
resurrection;
8. Evil souls die with their
bodies;
9. The human seed produces both the body
and the soul;
10. The elect are justified by the mercy
and love of God; the death of Christ was not an atonement but a demonstration
of divine love. (James Edward McGoldrick, Baptist Successionism: A Crucial
Question in Baptist History [ATLA Monograph Series 32; Metuchen, N.J.: The
