There is debate about when Christianity was first introduced; it was no later than the 4th century, probably much earlier. According to Bede , missionaries were sent from Rome by Eleutherius at the request of the chieftain Lucius of Britain in 180 AD, to settle differences as to Eastern and Western ceremonials, which were disturbing the church. There are traditions linked to Glastonbury claiming an introduction through Joseph of Arimathea , while others claim through Lucius of Britain .  By 410, during the Decline of the Roman Empire , Britain was left exposed by the end of Roman rule in Britain and the withdrawal of Roman army units, to defend the frontiers in continental Europe and partake in civil wars.  Celtic Christian monastic and missionary movements flourished: Patrick (5th-century Ireland) and in the 6th century Brendan (Clonfert), Comgall (Bangor), David (Wales), Aiden (Lindisfarne) and Columba (Iona). This period of Christianity was influenced by ancient Celtic culture in its sensibilities, polity, practices and theology. Local "congregations" were centred in the monastic community and monastic leaders were more like chieftains, as peers, rather than in the more hierarchical system of the Roman-dominated church. 
Dear Pamela,As a Brit, it’s nice to see someone from ‘over the pond’ who’s got most of the information about Afternoon Tea correct for a change: I now live in Vinci, Italy (yes where Leonardo was born), and now offer afternoon tea to Italians in our home dining would take you to task on one item in your article,(there’s always a critic!) and that is about Cream Tea in which you say: “Cream Tea — A simple tea service consisting of scones, clotted cream, marmalade or lemon curd and tea.” Cream Tea traditionally consists of scones served with clotted cream and strawberry said that if people prefer to have their scones (and it’s pronounced ‘skons’ as far as I’m concerned),with an alternative, I have no problem with that, it’s a free world (supposedly)!For example I sometimes fill my Victoria Sponge with lemon curd instead of the traditional raspberry jam and fresh raspberries both of which balance well with a nice cup of sweet Luck with the book!
