By selfishness I was not speaking of economics. Where I would agree that self interest is a good way to actually promote economic opportunity.
I meant selfishness of spirit. The denial of another's personhood and the idea that some elites KNOW what is best for society at the expense of the individual. This selfishness promotes abortion, euthanasia, and situational ethics. Why is this? Because their definition
of personhood and quality of life is based on their own personal, subjective morals and ethics.
Subject not to an outside external unchanging Creator who gave definite answers to the questions of right and wrong. But to an ever evolving moral standard based on the individual's world view. They can never be wrong and public policy should follow their conclusions. To me that is pretty darn selfish.
Christian spirituality is unselfish. Its foundation is the teachings of God as revealed in the Bible and (for Catholic and Orthodox )the Tradition of the Apostles. The moral and ethical teachings rest heavily on the dignity of the person. Life is worthy and sacred. It is to be celebrated and protected.
Only by submitting to God in these things can we be assured of not being in error. We are all sinners and without His word we would too easily fall into the trap of selfishness and disregard for others.
That's OK. All selfishness is of the same cloth, economic or not. And I believe that we would do well with more of it, in triumphant variety.
