I can think of one quite easily! I am in the UK where the influence of religion on politics is very much positive IMO. For example, we have an established church that often speaks up for the poor, against war, etc. Religion is in the forefront of practical action: it is a disgrace we need good banks, but the religious took the lead in filling that need (I see the same around the world too).
Also, historically we would not have democracy as we know it without the moral framework of religious ideas. I am guessing you are American and the idea of separation of church and state can be traced back to a long line of development that started with "give to Caesar what is Caesar's". Even in the UK, despite the efforts of Henry VIII, state control of the church faded and we are a de facto secular democracy.
Yes, my examples and arguments are all Christian, but different religions have different values and histories so you cannot generalise across all of them and I am sticking to what I know. I also think taking a long term historical view makes it look a lot more positive. Have you read Dominion by Tom Holland?
