What influence did Christianity have on people and their communities? Well, one of the primary influences Christianity had was that it ended infanticide and polygamy, which fall under the category of living sacrifices. Additionally, Christianity changed women. Normal instances that would occur were condemned, such as incest, birth control, and abortions were all considered to be unnecessary and ethically wrong in the eyes of Christianity. Christianity also transformed communities by contributing and serving to those who were unfortunate. They built orphanages, schools, shelters for homeless people, and many other beneficial factors. Christianity overall had an influence on people and their communities by encouraging more optimistic activities and degrading things that were seen as morally or ethically wrong, despite not being in the same position of those who experienced it.
