In a footnote in chapter 4 (Jesus Reveals John in Malachi), we mentioned that the unanimous testimony of the Early Church Fathers was that Mark’s Gospel is the faithful recounting of the preaching of the Apostle Peter.

Peter’s Favorite Adverb

Adding weight to this historical testimony is the energetic brevity of the accounts in Mark’s Gospel, and Mark’s frequent use of the adverb εὐθύς (eu-thús). The word appears in the New Testament 59 times; of those occurrences, it functions 51 times as an adverb, and is rendered (depending on your translation) as immediately or as soon as. Mark (or Peter, if you prefer) uses εὐθύς / euthús adverbially 41 of those 51 times, and it seems like we can almost listen through Mark’s ears to Peter’s animated and enthusiastic style of preaching and testifying.

Even Luke, in relating the Acts 10:16 description of the vision-sheet being taken up from before Peter’s eyes, uses euthús / εὐθύς to describe the sheet’s disappearance. That’s very appropriate, since the story would have originally come from Peter’s personal testimony about the incident! We might say of Peter that his “middle name” was euthús / εὐθύς, whereas Mark (also called John Mark) wasn’t exactly a barn burner, at least early in his career. (See Mark 14:51-52, where Mark makes an autobiographical stamp in his Gospel, as well as Acts 13:13; 15:37-39.)

Adjectivally Speaking

Peter uses euthúsεὐθύς as an adjective in 2 Peter 2:15, when he describes the false prophets and teachers as having “forsaken the right way.” When used as an adjective, rather than an adverb, euthús / εὐθύς means straight or right or upright. In this adjectival use, the word ties back directly and indirectly to our discussion of John the Baptist. As a direct connection, it’s the word used to describe John’s Isaiah 40:3 mission (e.g., “Make His paths straight”euthús / εὐθύς — in Matthew 3:3; Mark 1:3; Luke 3:4; as well as “the crooked will become straight”euthús / εὐθύς — in Luke 3:5).

Indirectly, when thought of in terms of heart prep­a­ra­tion, John the Baptist’s “heart-straight­en­ing” minis­try is contrasted with the spiritual state of Simon Magus and how Peter has to deal with him. In Acts 8:21 the Apostle re­bukes the magician, using this same word, when he says, “Your heart is not euthús / εὐθύς / straight / right be­fore God.”

Similarly, before Paul lowers the spiritual “boom” on Elymas the sorcerer in Acts 13:10, he demands: “Will you not cease to make crooked the euthús / εὐθύς / straight ways of the Lord?”3

And perhaps there’s even a twinkle in the Holy Spirit’s Scripture-inspiring eye when He chooses a street address for the blind Saul of Tarsus to complete his conversion process and get “straightened out.” When the Lord visits faithful Ananias in a vision (Acts 9:10), He tells him that Saul will be found “on the street called Straight” — euthús / εὐθύς (Acts 9:11)!

  3. Luke describes Elymas as “a Jewish false prophet” (Acts 13:6, where his other, that is, Jewish name is given as Bar-Jesus, i.e., “son of Joshua” in Aramaic). How opposite Elymas’ “ministry” is to that of John the Baptist! John’s commission (as noted previously) was to make Messiah’s paths straight (Luke 3:4, euthús / εὐθύς) and to oversee the crooked becoming straight (Luke 3:5, euthús / εὐθύς). But Elymas, as “an enemy of all righteousness,” continually worked at making crooked the straight (euthús / εὐθύς) ways of the Lord” (Acts 13:10), apparently in his controlling bid to turn Proconsul Sergius Paulus “away from the faith” (Acts 13:8).
