The model that Ham proposes for species diversity is widely criticized beyond Ross and others. However, that is not my problem with Ham. My problem is that he states people who do not hold to six literal day creation are not Christians. There is hardly a creditable theologian of philosopher who holds this view. Ham would also have to extend this argument to Church fathers.
Yes, I am tired of people who take a minor detail - adding the genealogies in Genesis and extrapolating the age of the earth - and somehow this is a salvation issue. You know most of them would mock any reference to the Church Fathers.
I’ve tuned in to Ken Ham’s message for many years, and I am unfamiliar with him stating categorically that people who don’t believe in six literal days of creation are not Christians. I would think his position was more that they were in error, but certainly may well be Christians in spite of their error. Being he is reformed in his soteriology (IIRC), he would be unlikely to reduce salvation to a pop quiz. Do you have a specific quote in mind?
