Albert Rhett Stuart was consecrated as the sixth bishop of the Episcopal Diocese of Georgia on October 20, 1954 in St. Pauls, Augusta. He had been elected during the diocesan convention of 1954 when seventeen persons were nominated to succeed Bishop Barnwell. Even with the large field of candidates, Stuart was elected on the second ballot. He was then serving as the Dean of Christ Church Cathedral, New Orleans, and had previously served as rector of the Church of the Redeemer in Greenwood, South Carolina and as rector of St. Michael's, Charleston. He was a graduate of Virginia Theological Seminary.
Eighteen months after becoming the diocesan bishop, Stuart told the convention meeting May 8–9, 1956 at St. Thomas' Episcopal Church in Thomasville,
People are discovering that a life full of gadgets is no satisfactory substitute for a life lived in the power and presence of God.
He went on to tell that Diocesan Convention that there were six steps needed for the Diocese to "fulfill her responsibility in this generation and improve her evangelistic witness." He named these as:A renewal of confidence and conviction that it is the mission of the Church "to proclaim her Lord as the Way, the Truth, and the Life for all Mankind." For this he recommended year-round use of Church Schools.
The diocese should appreciate the magnitude of her present opportunity. He encouraged direct evangelistic effort saying, "It is high time the Episcopal Church rose from her dignified posture of waiting to be discovered...and went out into the byways and hedges seeking souls for whom her Lord died."
New congregations should be established in areas where the Church had no work and in newly developing urban communities.
Accelerated support for the Church's University of the South at Sewanee.
Consideration of the sanctity of the Christian marriage partnership as a basic factor in the problem of human relationships.
Finally, he expressed concern over the racial problem, urging Churchmen to be vigilant "lest the fear and prejudice surrounding us infiltrate our thinking and confuse us as to our clear duty." He reminded those gathered of the many years in which white and colored Churchmen had "known their unity in Christ and have labored together in one fold under one shepherd."
Henry Louttit, recalls in his booklet, Saints of the Diocese of Georgia how Bishop Stuart was often the only white voice for integration in Savannah willing to speak on TV. He remembers him speaking up for integration on a visit to Trinity Episcopal Church in Stateboro saying,
This is a free country. You can belong to any kind of church you wish, but the Episcopal Church has never asked anyone why they were coming to the church. We are not starting asking people now. This church is open to anyone who wishes to worship.
He also told a Diocesan Convention that,
The solution of the problem of our society lies not in the realm of law but in the realm of faith and grace.
In 1957, Stuart dedicated a newly acquired Diocesan House on East Bay Street in Savannah as the diocesan headquarters. At that time, there were 9,976 communicants in the Episcopal Diocese of Georgia.
He served as diocesan bishop through 1971. He died two years later and was buried on Holy Saturday of that year, April 21, 1973.
In 1940, he received anhonorary degree in Doctor of Divinity from Oglethorpe University.
