Well in the uk they brought education to the poor because most schools for the poor were church schools.
They use to act as a welfare fallback for the desperately poor, and tickled the conscience of the rich who wanted to be seen to help. Years ago there was no benefits.
They gave people a sense of community ( the church was central in each village) and a sense of place ( even if we don't now agree with how they saw it)
They gave importance to key stages in life, such as birth, becoming an adult, marriage and death. Also the seasons such as harvest.
They struggle now to maintain a part of our history in old churches, which are often beautiful and well worth keeping.
I wouldn't say they have always been tolerant of different beliefs, because they haven't.
But when life got really hard the church was someone people in the community could take their problems too.
Nowadays it's different.
Welfare has become secular, so have things like school ...... Relatively speaking.
The church enabled people to do things for the poor without having to do so personally or being in the position of dealing with beggars directly.
