"Struggling to Recover a Catholic Sense"

VATICAN CITY, MARCH 3, 2007 (Zenit.org).- Here is the text Auxiliary Bishop Anthony Fisher of Sydney, Australia, delivered at the conference sponsored by the Pontifical Academy for Life and held in the Vatican last Friday and Saturday. The theme of the conference was "The Christian Conscience in Support of the Right to Life."

Our dissenting brothers and sisters who choose to separate themselves from the Church by mistakenly appealing to a malformed or defective conscience in rejecting the Church's teachings on abortion, euthanasia, sodomy and homosexuality, embryonic stem cell research, artificial contraception, etc., would do well to read this article with an open and uncluttered mind, in a spirit of Christian docility.
