The failure to protect life in its most vulnerable stages renders suspect any claims to the ‘rightness’ of positions in other matters affecting the poorest and least powerful of the human community. If we understand the human person as ‘the temple of the Holy Spirit’ – the living house of God – then these latter issues fall logically into place as the crossbeams and walls of that house. All direct attacks on innocent human life, such as abortion and euthanasia, strike at the house’s foundation [emphasis in the original]. These directly and immediately violate the human person’s most fundamental right – the right to life. Neglect of these issues is the equivalent of building our house on sand. Living the Gospel of Life: A Challenge to American Catholics, 23.
“Thou shalt not kill!” God wrote this commandment in the conscience of man long before any penal code laid down the penalty for murder, long before there was any prosecutor or any court to investigate and avenge a murder. Cain, who killed his brother Abel, was a murderer long before there were any states or any courts or law. And he confessed his deed, driven by his accusing conscience: “My punishment is greater than I can bear. . . and it shall come to pass, that every one that findeth me the murderer shall slay me” (Genesis 4:13-14)”
