The Anglican Catechism
The new Anglican catechism was authorized and published in 2014. The entire catechism is worthy of study and contemplation by believers in Christ. As is typical with catechisms, several primary ancient documents of Scripture and the Church are commented on and constitute an interpretation accepted by the church: The Ten Commandments, The Lord’s Prayer, and The Apostles’ Creed. Questions 301-308 address the Sixth Commandment “Thou shalt not kill.” The interpretation given in this catechism is consistent with the other catechisms of the Christian Church.
The Westminster Catechisms
The Westminster catechisms teach that the Ten Commandments are a summary of the Moral Law of Scripture. The Westminster Larger Catechism addresses protection and care for innocent human life under the Moral Law (Questions 91-150). See Questions 134-136 regarding the Sixth Commandment: “Thou shalt not kill” which includes “protecting and defending the innocent.” This link is to excerpts from the catechisms on what constitutes the Moral Law of Scripture and its application, particularly the Sixth Commandment.
