He was consecrated first Bishop of Plymouth on 25 July 1851,[2] having previously been rector of the church of St. John the Evangelist in Salford.
"In private life Archbishop Errington was gentle and affectionate, and his friends were warmly attached to him; but in his official relations he was stern and inflexible.
"[1] In October 1855, Errington was sent as temporary administrator to the Diocese of Clifton, where Prior Park Seminary was in financial default.
[5] Two years later, Henry Edward Manning was appointed Provost of Westminster and he established in Bayswater his community of the Oblates of St Charles.
Meanwhile he had been helping both Bishop Goss of Liverpool and Archbishop Cullen of Dublin with various administrative matters and ordinations.
[2] Manning recommended that the Vatican ask Errington to take on the task of preparing for the restoration of the hierarchy in Scotland,[7] but after considerable hesitation he declined.
