Doubting Thomas is a term that is used to describe someone who will refuse to believe something without direct, physical, personal evidence; a skeptic.
The term is based on the Biblical
account of Thomas
, who doubted the resurrection
and demanded to feel Jesus' wounds before being convinced (Bible (King James)/John#20:24
), although the Bible does not mention if actual contact took place. After seeing Jesus alive and being offered the opportunity to touch his wounds — according to the author of the Gospel of John
— Thomas professed his faith in Jesus; on this account he is also called Thomas the Believer
