Edwards was born to a Latter Day Saint family in Birmingham, England. During the First World War Edwards, as a conscientious objector, refused to serve in the British military when conscripted. Having been denied recognition by his local Military Service Tribunal, he was arrested, brought before the Magistrates' Court and handed over to the army. At a court-martial in Worcester on 21 December 1916 he was sentenced to 112 days imprisonment with hard labour, which he served in Wormwood Scrubs. On 30 January 1917 he was interviewed by the Central Tribunal, sitting in the prison, who found him to be a "genuine" conscientious objector, after all, and offered him admission to the Home Office Scheme, whereby conscientious objector prisoners could be released on condition of performing civilian work under civilian control. Edwards was transferred to Princetown Work Centre, set up in the erstwhile Dartmoor Prison, where he remained until the Scheme was wound up in April 1919.
Edwards immigrated to the United States to join the main gathering of RLDS Church members in Iowa and became a full-time missionary in 1920. On 13 October 1922, RLDS Church president Frederick M. Smith selected Edwards as an apostle of the church. Upon joining the Council of Twelve Apostles, he was selected as the organization's secretary. Frederick Smith died in 1946 and his brother Israel A. Smith was selected to succeed him. Israel Smith chose John F. Garver and Edwards as his counselors in the First Presidency. When Smith died in 1958 and was succeeded by his younger brother W. Wallace Smith, Edwards was retained as a member of the First Presidency. On 18 April 1966, Edwards was honorably released from membership in the First Presidency and replaced by Duane E. Couey. At this time, Edwards was officially encouraged to "pursu his talents of writing and teaching".

In 1938, Edwards published the first edition of his Commentary on the Doctrine and Covenants, a resource that was updated and republished throughout Edwards's life and is still used today in the Community of Christ in studies of the church's Doctrine and Covenants. From 1967 to 1976, Edwards updated the History of the Reorganized Church of Jesus Christ of Latter Day Saints to include material from 1896 to 1976, which comprises volumes 5 through 8 of the work.
