In 1877 the building of Trinity was completed, but the Venetian mosaics Brooks and Richardson wanted they could not then afford. It was not until the magnificent new altar and sanctuary of Maginnis & Walsh in 1938 that Trinity's chancel reflected that aspect of their dreams for Trinity, which Brooks called "America's glory forever". Here Phillips Brooks preached Sunday after Sunday to great congregations, until he was consecrated Bishop of Massachusetts in 1891. In 1886, he had declined an election as assistant bishop of Pennsylvania. He was for many years an overseer and preacher of Harvard University. In 1881 he declined an invitation to be the sole preacher to the university and professor of Christian ethics. On April 30, 1891 he was elected sixth Bishop of Massachusetts, and on the 14 October was consecrated to that office in Trinity Church.
