From the mention of "ruin", I'm guessing it was the church mentioned as being severely damaged by a V1 on 13-Aug-1944. See the
Flying Bombs and Rockets site where, about half way down it says:
"This was the second of 5 V weapons that fell in a very small area around St Olaves Hospital in the lower road causing major devastation. There was severe damage to Rotherhithe Great Hall (Town Hall) a church and St Olaves Hospital which suffered damage to a third of its buildings. 100 other houses and buildings in the surrounding area were damaged." and some other mentions of the Neptune Street are.
I have a similar interest in several churches on my area that were destroyed in WW2. Apart from a little information, including deeds such as the OP has, and a few photographs kept by my late father and grandfather who were leading members of one of them, my only recourse is to go through local newspapers (not on line). In the days when churches were the centres of communities and so widely reported, there are a lot of mentions, mostly the expected churchy activities like women's meetings, missionary evenings, youth activities, sports clubs, fund-raising for good causes, soup kitchens, BMDs, wartime rolls of honour, comings and goings of ministers, etc., etc.
Compensation was paid for churches damaged in bombing but it wasn't necessarily enough to rebuild and could be used to open new churches elsewhere, whilst the members of the bombed church joined up with another of the same denomination locally.
