32 CFR 1636.3: Basis for classification in Class 1-A-0.

(a) A registrant must be conscientiously opposed to participation in combatant training and service in the Armed Forces.

(b) A registrant's objection may be founded on religious training and belief; it may be based on strictly religious beliefs, or on personal beliefs that are purely ethical or moral in source or content and occupy in the life of a registrant a place parallel to that filled by belief in a Supreme Being for those holding more traditionally religious views.

(c) A registrant's objection must be sincere.
