There are three churches at Rendlesham, St Gregory's in the old village and St Felix in the new village, and now Grace Church.

Rendlesham St Gregory is in the old village, dedicated to St Gregory the Great, is late mediaeval and has served this community for around seven hundred years. St Felix Rendlesham is in the new village, and is dedicated to St Felix of Dunwich. It began life in the 1940s as the chapel for the Bentwaters airbase, and since 2000 has been serving the rapidly-growing new village built on the old airbase site.

These two churches offer contrasting and complementary styles of worship. Services at St Felix' Church usually feature modern worship songs led by one of the worship groups, and there is a children's group, the Holy Hurricanes, who go out to their own activities during the service and return before the end to show the rest of the congregation what they have been doing. Services at St Gregory's Church are more traditional in style, with hymns accompanied by the organ.

There is one Parochial Church Council (PCC) for the parish, where both churches are represented and support each other. See Rendlesham Churches.

But there is now also Grace Church Rendlesham which has been meeting in Rendlesham School since the beginning of 2019. Grace Church originated in the villages of Tunstall and Sudbourne over 200 years ago but the chapels in those villages are now too small for the growing community that is the church. As about two-thirds of the church live in Rendlesham, the school was the obvious location to meet in the village and provides plenty of space for family worship and also for the children’s groups that run during the second half of the service on Sunday mornings.
