In contrast to secular buildings, stone was used from very early on to build churches, although a single wooden example has survived at Greensted Church, which is now thought to be from the end of the period. Bede makes it clear in both his Ecclesiastical History and his Historiam Abbatum that the masonry construction of churches, including his own at Jarrow, was undertaken "morem Romanorum", "in the manner of the Romans", in explicit contrast to existing traditions of timber construction. Even at Canterbury, Bede believed that St Augustine's first cathedral had been 'repaired' or 'recovered' (recuperavit) from an existing Roman church, when in fact it had been newly constructed from Roman materials. The belief was "the Christian Church was Roman therefore a masonry church was a Roman building".
