On 2 December 1940, an incendiary bomb set fire to the building, destroying the chancel and nave of the church.[2] Only the tower, narthex, and sacristy remained standing.[3] W. H. Randoll Blacking was the architect chosen to reconstruct the church, but, after much delay, he died before work could begin.[2]
In the 1960s, it was once more decided that the rebuilding of the church should go ahead and Robert Potter, Blacking's partner, was selected as the architect.[2] He reorientated the church so that the altar now faces East.[1] The altar itself is free standing and is set under a ciborium, a four-columned indoor roof.[1][2] Behind the font is a series of stained glass windows made from fibre glass and designed by John Piper.[1][2] The new nave and altar were consecrated on 1 July 1967.[2] The same year, a stained glass window designed by Christopher Webb (another former partner of Blacking) was installed in the east window of the narthex;[1] it was Webb's last window (Webb having died the previous year).[4]
In 1978, the parish of All Saints Clifton was joined with that of St John's Clifton to form the Parish of All Saints with St. John Clifton.[3][5] St John's Church was declared redundant in 1980.[3][6]
