Mark 8:22-25 has Jesus heal a blind man at Bethsaida by spitting directly on his eyes and laying hands on him — twice, because the first attempt only half-worked. John 9:1-7 has Jesus heal a blind man in Jerusalem by spitting on the ground, mixing clay, anointing the man's eyes, and sending him to wash in the Pool of Siloam. Different cities, different methods, different timeline, and a different number of steps. Apologists treat them as separate events; the literary parallels suggest John has reworked the Markan tradition into something more dignified.
People have answered this in several ways; GEBible presents them as equal peers.

He came to Bethsaida. They brought a blind man to him, and begged him to touch him. He took hold of the blind man by the hand, and brought him out of the village. When he had spat on his eyes, and laid his hands on him, he asked him if he saw anything. He looked up, and said, “I see men; for I see them like trees walking.” Then again he laid his hands on his eyes. He looked intently, and was restored, and saw everyone clearly.
And as Jesus passed by, he saw a man which was blind from his birth. ... When he had thus spoken, he spat on the ground, and made clay of the spittle, and he anointed the eyes of the blind man with the clay, And said unto him, Go, wash in the pool of Siloam, (which is by interpretation, Sent.) He went his way therefore, and washed, and came seeing. John 9:1-6

As he passed by, he saw a man blind from birth. His disciples asked him, “Rabbi, who sinned, this man or his parents, that he was born blind?” Jesus answered, “This man didn’t sin, nor did his parents; but, that the works of God might be revealed in him. I must work the works of him who sent me while it is day. The night is coming, when no one can work. While I am in the world, I am the light of the world.” When he had said this, he spat on the ground, made mud with the saliva, anointed the blind man’s eyes with the mud,
Examining the tension
What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Genuinely disputed among scholars
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
At face value Mark 8:22-26 and John 9:1-7 describe two different healings. The settings differ (Bethsaida versus Jerusalem), the protagonists differ (an anonymous man brought by others versus a man blind from birth whom Jesus initiates contact with), and the outcomes differ (a two-stage cure with an intermediate stage of partial sight versus an immediate single cure after washing). On the strict question of historical fact, the apologetic position — represented by Craig Blomberg and the broader harmonist tradition — is sound: nothing requires these to be the same event, and the Gospels report many healings, so two saliva miracles are no more troubling than two feedings or two anointings. The Synoptic Birger Gerhardsson model of multiple comparable acts within an itinerant ministry is not implausible. To that extent the contradiction, framed as a bare factual collision, is overstated.
The more substantive issue is literary and source-critical, and here the tension is real. Mark 8:22-26 is the single most plausible synoptic candidate for what John 9 has reworked. Joel Marcus catalogs the shared elements: the use of saliva, the laying on of hands, a process that unfolds in stages, and a movement from blindness to confessed sight. Mark's pericope is also conspicuous for being one of only two Markan miracles (with the Decapolis deaf-mute of Mark 7:31-37, which also uses saliva) that both Matthew and Luke omit entirely. The standard redaction-critical explanation is that the two-stage failure — Jesus asking 'Do you see anything?' and getting the famous reply that men look 'like trees, walking,' requiring a second touch — was theologically awkward. A Messiah who needs a second attempt does not fit the later evangelists' Christology, so they cut it. Mark himself almost certainly intended the two-stage cure symbolically, framing it between the disciples' dull-sighted misunderstanding (8:14-21) and Peter's still-partial confession at Caesarea Philippi (8:27-30): the disciples, like the man, see but not yet clearly.
John 9 keeps the saliva — a detail apparently too embedded in the tradition to discard, and one paralleled in Hellenistic healing lore (Tacitus, Histories 4.81, and Suetonius, Vespasian 7, both report Vespasian healing a blind man with spittle, indicating saliva was a recognized cultural sign of healing power) — but replaces the messy, repeated touch with a single competent act mediated through washing in the Pool of Siloam. John then supplies an interpretive gloss found nowhere in Mark: Siloam means 'Sent' (apestalmenos), tying the cure to Johannine sending Christology. Raymond Brown treats John 9 as drawing on traditional miracle material that John has theologically elevated, and the cumulative parallels make a developmental relationship more economical than pure coincidence.
The apologetic rejoinder — these are simply two distinct events — must then explain why Jesus employed an unusual saliva-and-clay technique that appears nowhere else in his recorded ministry, in two different cities, producing two structurally parallel narratives. That is possible but less parsimonious than the redactional account, in which one underlying tradition generated both. John Meier's analysis of the saliva traditions notes their relative rarity and their tendency to attract embarrassment-based omission, which is why their preservation in Mark is a mark of antiquity.
Net assessment: if the question is 'were these the same factual event,' the harmonization holds and the contradiction is overstated. If the question is 'how does the Gospel tradition portray Jesus curing blindness,' the texts give two non-overlapping methods, and the most economical explanation for the John 9 portrayal is a Johannine reworking of the Markan tradition rather than an independent second miracle.
Where the critical reading lands: harmonizable as distinct events; better explained as Johannine redaction of the Markan tradition.
