One such creationist who has modified Gosse's theories on appearance of age is John C. Whitcomb. In 1961 he and fellow creationist Henry M. Morris published the book The Genesis Flood. In this book they claimed that since God created the earth in six literal days, it was necessary for Him to create it with "an appearance of being 'old' when it was still new" (Whitcomb and Morris 1961:233). They then emphasized the theological importance of this "grown creation." Whitcomb (1972) published a more recent book discussing appearance of age titled The Early Earth. In it, he argues that belief in creation with an appearance of age is a necessary part of Christian theology for various reasons, including the miracles of Jesus. With the miracle of feeding the multitudes it should take time to grow the grain for the bread and for the fish to mature and be caught. When Jesus turned water into wine, there is an assumed time needed for the grapes to mature, be harvested, and reach fermentation. When Jesus cured blindness or healed Lazarus, the people being healed were given the appearance that they had lived lives free of their ailments, when in fact they had not. Whitcomb cites these stories in the New Testament as examples in addition to the creation story in Genesis of an apparent but counterfactual history in the Bible. Whitcomb takes issue with Gosse, however, because he believes that God did not create an appearance of age where it was not absolutely necessary, such as with Adam's navel (Whitcomb 1972:41-43).
Creationist Kurt P. Wise echoes Whitcomb's sentiments about Christ's miracles being further evidence of appearance of age in his book Faith, Form and Time. Wise furthermore argues that "if God's purpose in creating something is fulfilled by creating it with an appearance of age.then He will do it" (Wise 2002:58-60).
Despite the fact that the appearance of age is strictly a philosophical and theological argument, the RATE team (which has generally been focused on attempting to use scientific methodologies to back up the young earth model) has also weighed in on the issue. For example, in reference to certain rocks containing Polonium halos that appear to have a long geological history, the RATE team concludeed that according to Genesis it is theologically possible for these rocks to have been created with an appearance of age (Snelling 2000:440-441).
