It is a Grade II listed building and the earliest of the four Roman Catholic churches in Worthing.

It is an active Roman Catholic parish church in the diocese of Arundel & Brighton and the Worthing deanery.

[citation needed] The church was built on land bought by Thomas Gaisford, owner of Offington Hall in Broadwater.

Previously Gaisford had allowed the new chapel he had built at Offington Hall to be used by the public from 1859.

[1] Originally designed by Henry Clutton in the style of French Gothic revival with an exterior built of red brick with Portland stone, the church was extended by Frederick Walters in 1897-1907 to include a baptistery and an extension to the porch and sacristy.
