bruce-you are quite right that worship can happen outside the church but many christians see meeting together as prescibed practise to be maintained even if not entirely happy about everything or everyone in the church.hebrews 10 v24,25.
if i were to be labeled,i suppose i would be non-conformist.i believe the bread and wine are symbolic of the blood and body of Christ and should be treated reverently during the eucharist but are ordinary otherwise.i would have no argument with anyone stricter, but for me it is substance of the symbol not the substance itself that matters.
