The bells of St Teresa's Church started ringing, which they are not wont to often do.
Perhaps this was to remind people that no Man may serve two Masters.
"No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon."
(presumably they do not quote this very often in City Harvest and other Propserity Gospel churches)
