Val Webb, author of In Defence of Doubt, is currently on a tour of the UK. Here she finds a motive which might explain why John's Gospel leaves the apostle Thomas' reputation so discredited.
I have always felt sorry for Thomas. Next to Judas, he drew the worst press for asking to see the evidence. Peter denied and deserted Jesus and became head of the church. Thomas, on the other hand, acted with integrity and earned a negative label - doubting Thomas.
