how to get to repulse bay from st. andrew church in HK?

From the church, you can walk to the Tsim Sha Tsui Station to take the Tsuen Wan Line to Central Station. Get out of the station from Exit A and walk to the Exchange Square Station, where you can take the bus line 6 or 6A to reach Repulse Bay Station. Then walk to the bay after you get off the bus.
