Believing in Jesus Christ also means having a new outlook on man, a look of trust and hope. Moreover, experience itself and reason show that the human being is a subject capable of discernment, self-conscious and free, unique and irreplaceable, the summit of all earthly things, that must be recognized in his innate value and always accepted with respect and love. He has the right not to be treated as an object of possession or something to manipulate at will, not to be reduced to a mere instrument for the benefit of others and their interests. The human being is a good in and of himself and his integral development should always be sought. Love for all, if it is sincere, naturally tends to become a preferential attention to the weakest and poorest. In this vein we find the Church's concern for the unborn, the most fragile, the most threatened by the selfishness of adults and the darkening of consciences. The Church continually reiterates what was declared by the Second Vatican Council against abortion and all violations of unborn life: 'from the moment of its conception life must be guarded with the greatest care'.... With regard to the embryo in the womb, science itself highlights its autonomy capable of interaction with the mother, the coordination of biological processes, the continuity of development, the growing complexity of the organism. This is not an accumulation of biological material, but a new living being, dynamic and wonderfully ordered, a new unique human being. So was Jesus in Mary's womb, so it was for all of us in our mother’s womb…there is no reason not to consider him a person from conception.
