Public Community Events are for the whole community to attend eg. the church and local community, friends, visitors to the area etc. All are welcome to attend.
'By invitation only Church events' are By Invitation Only. They are NOT public community events. They might be for internal training, group practices, planning or business meetings, private Bible study/prayer/worship etc.
'External Events' are located away from the church building. They may be organised or promoted by GBC.
