This image shows clearly many of the changes to the sanctuary that occurred early in the time of Father Maynard (vicar 1926-64). Following a long visit to England, the Continent and the Middle East in 1928, he returned with plans for the life of the parish, and changes to the interior of the church, based particularly on what he had seen in Anglo-Catholic churches.

The sanctuary now took on a very muted version of the continental revival baroque style being used in a number of English churches: many notable examples designed by Martin Travers exist. The altar was highlighted by being extended at each end, and placed on a tier of steps. At this point, the Last Supper mosaic was raised, taking the place formerly filled by the central window behind the high altar. From his travels, Maynard brought back the Italian baroque-style candlesticks and crucifix, and the fine English copy of the Thorwaldsen statue of Christ, which was placed on a ledge above the mosaic. Maynard here displayed his remarkable visual sense: the outstretched hands of the statue helped to redirect the gaze of viewers as their visual focus was drawn up the tall candles. Sitting on the altar are the missal and a set of altar cards (texts of prayers as a memory aid for the celebrant), the latter specially made for the church by a calligrapher and teacher at Firbank.
