Short answer: The words of Luke 1:68–70 are the prophetic song of Zechariah (the father of John the Baptist), but the Gospel writer who recorded and shaped that text is Luke — traditionally identified as Luke the physician, companion of Paul. Evangelical Christians typically treat Luke as the human author of the Gospel of Luke (and Acts), writing under the inspiration of the Holy Spirit.

Key points an evangelical would emphasize

– Who actually spoke the verses:
– The speaker within the narrative is Zechariah (a Judean priest of the division of Abijah), filled with the Holy Spirit and prophesying after John’s birth (Luke 1:67–79). Luke preserved Zechariah’s Benedictus.

– Who wrote (recorded) them:
– Luke the evangelist is the most-likely human author of the Gospel that contains Luke 1:68–70. Evangelicals hold that Luke, under divine inspiration, compiled and wrote the account.

– Identity and credentials of Luke (evangelical summary):
– Luke is mentioned in the New Testament as “Luke, the beloved physician” (Colossians 4:14) and as one of Paul’s companions (Philemon 24; the “we” sections in Acts imply his traveling with Paul).
– Early church writers (e.g., Irenaeus, Tertullian) also attribute the third Gospel and Acts to Luke.
– Many evangelicals consider Luke probably a Gentile and a highly educated writer, fluent and polished in Greek.

– Why evangelicals trust Luke’s account:
– Luke 1:1–4 explicitly describes his method: careful investigation and compilation from eyewitness testimony so that readers “may have certainty” about the things taught.
– The “we” passages in Acts and references to Luke in Paul’s letters support his firsthand association with key events and reliable sources.
– Evangelicals also point to Luke’s competent, polished Greek, interest in historical and geographical detail, and medical vocabulary as signs of an attentive, careful historian.
– Doctrinally, evangelicals affirm that Luke wrote under the inspiration of the Holy Spirit (2 Timothy 3:16), so his recording of Zechariah’s prophecy is both historically grounded and theologically authoritative.

– Typical dating and purpose (evangelical view):
– Many conservative scholars date Luke’s Gospel to the early 60s AD (some give a range within the 60s), with Acts completed later; the book is addressed to “Theophilus” and intends to present an orderly, trustworthy account of Jesus’ life, ministry, and the early church.
– Theologically, Luke emphasizes Jesus as the fulfillment of God’s promises to Israel and as Savior for Jews and Gentiles, a point made clearly in Zechariah’s song (Luke 1:68–79).

Why this matters for Luke 1:68–70
– Evangelicals read these verses as Luke’s faithful report of Zechariah’s Spirit-inspired declaration that God has visited and redeemed his people and fulfilled covenant promises (rooted in the Abrahamic/Old Testament covenant). Because of Luke’s careful, historically grounded approach and the conviction of Scripture’s inspiration, evangelicals treat the passage as both historically reporting Zechariah’s words and as theologically authoritative teaching about God’s redemptive action in Christ.
