As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.
Problem, Cause, Solution
In Matthew 25:31-46 Jesus described ongoing problems in our society such as poverty and sickness. What are some of the causes? Poverty is caused by overpopulation, inadequate distribution methods, rising costs, inadequate education, unemployment and under-employment, environmental degradation, individual responsibilities, medical costs, sickness, greed, the cost and devastation of war, natural disasters, industrial changes, recessions, discrimination, pregnancy out of wedlock, disability, crime and unjust incarceration, immigrant status, gang presence, etc. How do we as Christians address those problems? Do we address the short-term need of feeding the poor, or do we address the political and economic issues that cause poverty? Some Christians address the direct need by activity in a soup kitchen. Others address the underlying causes by involvement in politics. Both address the problem, but Jesus only demanded that we at least start by giving the hungry food.
