Final answer:
Settlement houses demonstrated the Social Gospel movement's principles by providing community services to the urban poor, encompassing the Christian ethics of charity and living among those in need to directly improve social conditions.
Step-by-step explanation:
Settlement houses reflected the ideals of the Social Gospel movement by providing social services to the urban poor. These establishments were founded on the belief that Christians should actively improve the conditions of people in the secular world, a core tenet of the Social Gospel philosophy. Influential figures like Jane Addams and Lillian Wald opened settlement houses, such as Hull House and the Henry Street Settlement, offering a variety of services including daycare, educational classes, health care, and other forms of assistance to aid the working class and bolster social reform. By living and working within impoverished neighborhoods, the reformers engaged in direct service to the community, thereby enacting the ideals of Christian ethics and charity mentioned in the movement.
