the older part of the church may have been rebuilt using the previous stones at this time. By 1535, the position of rector of the parish was held by the person holding the position of Archdeacon of Anglesey, as part of the remuneration for that office; this is no longer the case. Further structural changes to the church were made in the early 16th century when some windows were added to the chancel. In 1852, restoration work took place to the nave and chancel under Henry Kennedy, architect of the Diocese of Bangor. The chancel was rebuilt, although the east wall and window were retained, and further windows were added in the church. St Cristiolus's Church is still in regular use and belongs to the Church in Wales. It is one of six churches in the combined benefice of Plwyf Seintiau Braint a Chefni. The other churches in the benefice are St Michael's, Gaerwen; St Ffinan's, Llanffinan; St Caffo's, Llangaffo; St Edwen's, Llanedwen; and St Mary's, Llanfairpwll. It is within the deanery of Malltraeth, the archdeaconry of Bangor and the Diocese of Bangor. The current incumbent (as of 2013), Emlyn Williams, was appointed as vicar of St Cristiolus's Church in 2007; before that, the position had been vacant for 20 years despite many attempts by the Church in Wales to fill it. He is assisted by one associate priest and two associate curates. Services are held every Sunday morning, alternating between a bilingual service of Holy Communion and a service of Morning Prayer; there are no midweek services. People associated with the church include Henry Maurice (elected Lady Margaret Professor of Divinity at the University of Oxford shortly before his death in 1691; his father, Thomas, was the perpetual curate of the church) and the 19th-century writer and priest Owen Wynne Jones (who was the curate for a time in the early 1860s). The 19th-century Calvinistic Methodist preacher Richard Owen was born in the parish, and is buried in the graveyard that surrounds the church.
