Actually the list provided did refer to 'Christian historians' who are recognized academic historians, but heir publication and specialty was not documenting a historical Divine Jesus. The classification of 'Christian historians; is odd since most historians in the West are Christian, There are Middlest historians that specialize in the ancient history surrounding Judaism, Christianity and Islam, but they are not on the list, @Spatan is the problem misrepresenting the list provided.
Yes, evangelical theologians do make claims that cannot be documented concerning the historical Jesus.
