Thomas Wanted Proof
“But prove all things; hold fast that which is good.” — 1 Thessalonians 5:21, Douay-Rheims
The case
Thomas said he wouldn't believe until he put his finger in the wounds. Everybody remembers him for that. Doubting Thomas. But look at what Jesus actually did.
The evidence
Every quotation below is printed in the words of the edition named under it. Nothing is paraphrased.
“Except I shall see in his hands the print of the nails, and put my finger into the place of the nails, and put my hand into his side, I will not believe.”John 20:25 (Douay) — read it at the source
“Thomas answered, and said to him: My Lord, and my God.”John 20:28 (Douay) — read it at the source
“The unbelief of Thomas is more profitable to our faith, than the belief of the other disciples.”St. Gregory the Great, Homily 26 on the Gospels, as given in the Catena Aurea on John 20 (Newman/Parker ed., PD) — read it at the source
“by feeling in his Master the wounds of the flesh”St. Gregory the Great, Homily 26 on the Gospels, as given in the Catena Aurea on John 20 (Newman/Parker ed., PD) — read it at the source
“Jesus saith to him: Because thou hast seen me, Thomas, thou hast believed: blessed are they that have not seen, and have believed.”John 20:29 (Douay), FULL verse so the blessing is not cut from its context — read it at the source
“But prove all things; hold fast that which is good.”1 Thessalonians 5:21 (Douay) — read it at the source
What’s established, and what isn’t
What the sources support, claim by claim — each one checked against the sources listed at the foot of this page:
- John 20:24-29 Douay wording for vv. 25, 27, 28, 29
- 'Eight days later' (John 20:26 'after eight days')
- Gregory the Great: Thomas's unbelief profited our faith more than the faith of the believing disciples
- Tradition: Thomas preached in India and was martyred there
- Honest questions vs deliberate doubt (CCC 2088, paraphrase)
- 1 Thess 5:21 Douay wording
Where the record stops short:
- That Thomas preached in India and was martyred there is tradition, not record.
- Scripture tells us what Thomas said and what Jesus answered. It does not tell us what Thomas did with the rest of that week.
For your men’s group
- What is the difference between the kind of doubt Thomas had and the kind a man uses to avoid a decision?
- Jesus gave Thomas the proof he asked for. When has a plain answer actually settled something for you?
- Which of your own questions have you never said out loud to another man, and what would it cost you to say one this week?
