Of course.........the Atheist has a moral code......or they would find themselves imprisoned for crimes against humanity, as any societies morality is reflected within that societies LAW.
Its not an issue of the existence of morality, its an argument of where and how the moral compass of mankind came into existence. The Atheist must argue that morality was innately evolved from lower life forms found to exist in nature, if not they must confess to the transcendence of morality and a moral lawgiver. But they want and demand everyone to believe that morality has evolved from animals such a mice, frogs, fish......etc.,
The major problem that the Atheist must contend with is the fact that all moral codes from all around the world are found to exist within the written record of the Holy Scriptures.
I defy anyone to present a moral code that is not recorded in scripture. Because there might be more moral codes than the Atheist wishes to obey in no indication of an errant moral code.
A small list of moral codes found to exist in scripture. 1. Avoid hatred (Matt. 5:21-22) 2. No lustful thinking (Matthew 5:28) 3. No unfair judgements (Matt. 7:1-2) 4. Love of enemies (Matt. 5:44) 5. Reconciliation (Matt. 5:24) 6. Non-resistance (Matt. 5:38-39) 7. Avoiding anxiety (Matt. 6:25,29) 8. Self examination (Matt. 7:3-5) 9. Respect for government (Rom. 13:1-7) 10. Equality of man (James 2:1-4) 11. Universal brotherhood (Matt. 23:9) 12. Forgiveness (Mark 11:25) 13. Thrift and Industry, honest hard work (Eph. 4:28) 14. Progress (Heb. 6:1) 15. The value of truth (2 Cor. 13:8) 16. Truth as the basic tenet of FREEDOM (John 8:32) 17. Humility (Luke 14:11) 18. Benevolence (Acts 20:35) Honesty (Rom. 12:17) 19. A single standard of morality (as morality exists in all civilized societies) (Eph. 4:4) 20. Unselfishness (12:10)
Referenced from a 1929 debate between a Christian and an Atheist. During the time period when the SCOPES MONKEY trail was the secular in vouge progressive band wagon to jump aboard.
And we can't exclude the basic 10 commandments of morality found within the Holy Scriptures, that are common to most societies on earth. Except those societies where NATURE and SAVAGERY rules. (Kind'a contradicts the basic concept of an evolving morality from nature.) Just like the existence of modern day primates.....the supposed parent of all mankind..........I guess the one's that sill exist into the modern era where just to stupid to evolve.....or they missed the memo concerning natures mission statement.
