From the Protestant perspective, you are referring to the phenomenon characterized as the "Social Gospel". That it is thoroughly pervasive in Protestantism is not evident. However, that it characterizes the theology of a number of "mainstream" Protestant denominations is a reality. A number of people in my family are prominent Presbyterian theologists and administrators. They are typical, aging, Berkeley, Marin, and Palo Alto liberals living off old money. These folks milk their congregations for money while they soft-sell the agenda.
