“Origen reminds his readers that doubting Thomas is not the only model of faith in the Scriptures. Faith is more than believing what was not seen with the eyes. Jesus said to his disciples, ‘Happy are your eyes for they see and your ears for they hear‘ (Matt. 13:16). His saying suggests that those who have seen with the eyes are happy, not just those who believed without seeing. Was not Simeon happy, asks Origen, when he saw the Christ child and “held God’s salvation in his arms.” Did he not say, ‘Lord, now let your servant depart in peace for my eyes have seen your salvation’ (Luke 2:29-30). Origen concludes that ‘faith complemented by vision is far superior to faith through a mirror.’ The disciples who saw Jesus alive after his death knew him by faith even though they could see him with their eyes.” (Robert Louis Wilken, The Spirit of Early Christian Thought, p. 179)
“The physical evidence that Thomas is invited to inspect is only a beginning, but, in human terms, perhaps an essential beginning for many on the road to faith. St. John the Theologian begins his first epistle by restating this evidence and its ultimate purpose: ‘That which was from the beginning, which we heard, which we saw with our eyes, which we observed, and which our hands touched, concerning the Word of Life…what we saw and heard we announced to you so that you might have fellowship with us as we have fellowship with the Father and his Son Jesus Christ’ (I Jn. 1.1-3), author’s translation).
The faith of Thomas was not born from a purely objective examination of empirical evidence. It could only emerge from the interface between a conscious acknowledgement of the evidence and an interaction between persons made initially possible through the senses. For the faith spoken so eloquently in Thomas’s declaration to Christ is not the affirmation of an idea or a fact, but a commitment of absolute trust in a Person. It is the necessary element, the sine qua non, for the journey toward union with the unknowable God, who yet through a relationship with his incarnate Word can be known.” (Daniel B. Hinshaw, Touch and the Healing of the World, p. 111)
