The great Jewish thinker Abraham Joshua Heschel wrote and spoke eloquently on the topic of ecumenism between Jews and Christians. Heschel observed that while dogma and tradition separate Jews and Christians, both traditions believe in the God of Abraham. Heschel asked Christians to take a theocentric approach to theology as opposed to a christocentric approach. The universe and human existence are not meaningless, empty phenomena devoid of purpose and reason. Rather, they are replete with meaning because they are created by God who possessed a specific design and intent when fashioning creation out of nothing.
Creation is seen as neither random nor as the product of impersonal forces.
On the individual level, this means treating others fairly and respecting the inherent dignity of the people we encounter daily. It means adhering faithfully to the commandments, of living a faith-life where our lives embody the aspirations of the religious language we use in prayer and liturgy. We speak of God as the ultimate reality conferring both rights and obligations upon us. We are expected to love the Lord God with all our heart and soul, and to love our neighbor as ourselves. You may not like the grimy, dirty homeless person on the street but your are obligated to feed him.
