Ambrosiaster

Ambrosiaster, also known as Pseudo-Ambrosius, is the name given to the unknown author of Commentaria in Epistolas Beati Pauli, an early commentary on the writings of the apostle Paul. While the work was initially attributed to St. Ambrose, Bishop of Milan, it was later questioned by Desiderius Erasmus in 1527 and his verdict has since been widely accepted by scholars. As a result, the name Ambrosiaster, or Pseudo-Ambrosius, is now used to refer to the author of this commentary.

Who was Ambrose of Milan?

The real Ambrose, also known as Aurelius Ambrosius, was the bishop of Milan during the fourth century. Prior to his religious career, Ambrose held a position in the Roman government as a consular prefect. He had a strong educational background and studied law, literature, and rhetoric. Ambrose was known for his exceptional oratory skills and even influenced Augustine, who was then a non-believer, to attend his speeches.

As bishop of Milan, Ambrose was highly regarded for his generosity towards the poor, his opposition to the Arian heresy, and his commitment to ethical conduct. However, he is perhaps best known for playing a significant role in Augustine's conversion to Christianity.

The Commentary and its Authorship

The manuscript attributed to Ambrosiaster does not provide any clues about its author. Internal evidence suggests that the commentary was written during the pontificate of Damascus (AD 366—384). The biblical quotations used in the work predate the Latin Vulgate, and references to ecclesiastical writers such as Tertullian, Cyprian, and Victorinus further support a dating in the mid- to late-fourth century.

Adding to the confusion surrounding authorship, Augustine credited parts of the commentary on Paul's letter to the Romans to Sanctus Hilarius. Despite the uncertainty surrounding the author's identity, the Commentaria in Epistolas Beati Pauli was highly regarded by scholars such as Augustine and Jerome for the quality of its exegesis.

The Significance of Ambrosiaster's Commentary

Considered one of the prominent Dominican scholars of his time, Sixtus Senensis, or Sixtus of Siena, described the Commentaria in Epistolas Beati Pauli as "brief in words, but weighty in matter." The biblical references found in Ambrosiaster's work predate the Latin Vulgate, making this commentary essential for textual criticism.

The Commentaria has played a crucial role in understanding the early interpretation of Paul's writings and has been influential in shaping theological discussions throughout history. Its insights into the biblical text have provided scholars with valuable perspectives on Pauline theology and have contributed to a deeper understanding of the early Christian Church.

Why This Matters

Understanding the authorship and historical context of biblical commentaries like Ambrosiaster's is crucial for interpreting Scripture accurately. By recognizing that Ambrosiaster was not St. Ambrose himself, we can avoid attributing ideas or interpretations to the wrong individual. Additionally, recognizing the influence that Ambrose had on Augustine's conversion can deepen our appreciation for their theological contributions.

By studying commentaries from different periods in history, we can gain insights into how early Christians understood and interpreted Scripture. This broader perspective allows us to engage with the biblical text more fully and appreciate its richness and depth.

Think About It

Consider how our understanding of Scripture has been shaped by historical figures like Ambrose and Augustine. How might their interpretations still impact our reading of the Bible today? How does knowing about the existence of commentaries like Ambrosiaster's enhance our appreciation for the scholarship and dedication of early Christian theologians?

Reflect on the importance of studying the historical context and authorship of biblical commentaries. How can this knowledge help us avoid misinterpretations or misattributions? How does a deeper understanding of the historical context of Scripture contribute to our faith?
