Recently, BioLogos published an infographic entitled “How do we Know the Earth is Old?” Many Christians have wondered what to make of this poster since BioLogos presents itself as an association of evangelical Christian academics committed to harmonizing science and conservative Christian faith. That sounds good, especially the word “conservative”, but their starting position is anything but orthodox. They promote evolution over millions of years, as taught by secular scientists, as truth, and that Christians must accept it. They do not concern themselves with how such acceptance undermines the authority and the message of Scripture itself.
Moses has a lot to say about the age of the earth, and ignoring this fact leads to heretical Christian teaching and very bad natural history.
To many the age of the earth may seem an innocuous topic but it has a massive impact on conservative Christian doctrine such as the integrity of the gospel. If the earth is billions of years old, as the BioLogos poster presents, then Jesus made mistakes in his teaching and the gospel is false. It is that simple, as we will see.
According to BioLogos, all we have to do is reinterpret Moses, Jesus, and Paul, and everything is harmonized. A historical Adam doesn’t matter, and Jesus’ Incarnation allows him to make errors concerning what the Father commanded him to say about the age of the world (Mark 10:6; Luke 11:50–51; cf. John 8:28). However, their ‘reinterpretations’ look nothing like what Moses, Jesus, and Paul actually said. Neither were such interpretations ever entertained in church history before the advent of long-age geology in the 18th century (on which see The Great Turning Point). The reasons are pretty obvious. If Jesus made mistakes, especially in his teaching ministry, then He is not perfectly trustworthy, as Christians have believed through the ages. If a historical Adam doesn’t matter, then the whole doctrine of salvation, as presented by the Apostle Paul, falls to pieces (see articles on Romans 5, Romans 8, and 1 Corinthians 15). One could say that there never has been a time when Jesus’ words about Moses have been more important for us to hear than now: “For if you believed Moses, you would believe me; for he wrote of me. But if you do not believe his writings, how will you believe my words?” (John 5:46–47).
