In 1841, a travelling tutorship took him to the continent; on returning, he published Sights and Thoughts in Foreign Churches and among Foreign Peoples (London, 1842), which he dedication to his poet friend William Wordsworth.
Ordained an Anglican minister, in 1843, Faber, became Rector of Elton in Huntingtonshire. However, a strong Methodist presence existed in the parish and Dissidents packed his church each Sunday in an attempt to ridicule his Catholic leanings. Few were surprised when in November of 1845, after a long and painful internal struggle, he left Elton and joined the Roman Catholic Church.
He founded a religious community at Cotton Hill, called Wilfridians over which He presided until his death. In spite of his weak health, an almost incredible amount of work was crowded into those final years. He published a number of theological works, and edited the Oratorian Lives of the Saints.
Faber put pen to paper to create some of the most profound and beautiful verse:
"For the heart only dwells truly dwells with it's treasure
And the langour of love capptive hearts can unfetter
And they who love God cannot love Him by measureFor their love is but hunger to love him still better"
