Criterion of multiple attestation

[6]: 15 Potentially reliable sources that scholars have considered to be independent of one another for the purposes of this criterion include:[4][8][9]: 9:12 For example, the "Kingdom of God" motif appears in "Mark, Q, special Matthean tradition, special Lucan tradition, and John, with echoes in Paul, despite the fact that 'Kingdom of God' is not Paul's preferred way of speaking.

[8]: 175 The words attributed to Jesus on the bread and wine during the Last Supper (found in Mark 14:22–25 and 1 Corinthians 11:23–26 (Paul), compare to John 6:51–58) and his prohibition on divorce (found in Mark 10:11–12, Luke 16:18 (attributed to Q), and 1 Corinthians 7:10–11 (Paul)) are examples of sayings that are multiply attested.

[8]: 175 [10]: 183  However, the Lord's Prayer, although found in both Matthew and Luke, evidently derives from their common source Q, and therefore cannot pass the criterion.

[4] (The Augustinian hypothesis posits that Mark and Luke used Matthew, so once again triple-tradition material would have originated in a single source).

[4] Finally, there are some sayings or deeds of Jesus that only appear in one form or source that scholars still consider historically probable.

Visualisation of the four-document hypothesis . In order to be both multiply and independently attested, it's not enough for a tradition to simply be found in two or three of the Synoptic Gospels . It needs to be attested in a combination of at least two out of the Marcan , Q , M , or L source materials. Otherwise, a non-Synoptic source is required to corroborate a tradition found in the Synoptics. [ 4 ]
What Jesus reportedly said about bread and wine at the Last Supper passes the criterion of multiple attestation. [ 8 ] : 175
