Answer:
The roots of the Unitarian movement lie mainly in the reformation of the 16th century. At that time people in many countries across Europe began to claim the right to read and interpret the bible for themselves, to have a direct relationship with God without the mediation of priest or church, and to set their own conscience against the claims of religious institutions.
Many people came to question orthodox Christian doctrine and to affirm beliefs of their own. These included:
the unity or unipersonality of God, as opposed to the doctrine of the Trinity – hence the name ‘Unitarian’;
the humanity, as opposed to the deity, of Christ;
the worth of human beings, as opposed to ideas of original sin, inherited guilt and innate depravity;
the universal salvation of all souls.
