Ambrose of Milan

Ambrose of Milan, also known as St. Ambrose, was a prominent figure in early Christianity. He was born in AD 339 into a Roman Christian family and became the first early church father to come from such a background. Ambrose is widely remembered for his fight against Arianism, his contributions to church music, his stance on the separation of church and state, and his mentorship of Augustine.

A Defender Against Arianism

Arianism was a heretical belief that denied the divinity of Jesus Christ. Ambrose played a crucial role in combating this false teaching. He firmly supported the Nicene Creed, which affirmed the full divinity of Jesus, and spoke out against Arian theology. His influence was so significant that both orthodox Catholics and Arians demanded that he become their bishop. This demonstrates the immense respect he commanded from both sides.

The Church's Independence from the State

Ambrose had a unique perspective on the relationship between the church and the state. Unlike many of his contemporaries, he believed that the church should not be morally subject to the ruling government but rather, the government should be subject to the moral authority of the church. He even went as far as banning Emperor Theodosius from communion until he repented for his involvement in a civilian massacre. This demonstrates Ambrose's strong belief in the church's independence and its role in holding rulers accountable.

Contributions to Church Music

Ambrose made notable contributions to church music during his time as bishop of Milan. He introduced the concept of congregational singing, which was somewhat controversial at that time. This innovation allowed ordinary believers to actively participate in worship through singing hymns together. Ambrose recognized the power of music in fostering spiritual connection and creating a sense of community among believers.

Mentorship of Augustine

One of Ambrose's most significant contributions was his mentorship of Augustine, who would go on to become one of the most influential figures in early Christian history. Augustine was deeply influenced by Ambrose's preaching and teachings. Ambrose played a key role in Augustine's conversion to Christianity and baptized him. Through their close relationship, Ambrose helped shape Augustine's theological understanding and encouraged him to pursue a life dedicated to serving God.

Legacy and Recognition

Ambrose's contributions to Western Christianity have had a lasting impact. He wrote the first known book on Christian ethics, which provided guidance for believers in living out their faith. His extensive library of writings, including works against Arianism, showcased his mastery of Greek and his ability to analyze previous theologians with depth. Ambrose's teachings on the role of the Holy Spirit, rejection of legalism, and support for personal faith resonated with many believers.

"When in Rome, do as the Romans do"

Ambrose was an excellent preacher known for his compelling sermons. One of his sermon quotes has become a well-known idiom: "When you are at Rome, live in the Roman style." This phrase highlights the importance of adapting to local customs without compromising one's faith. Ambrose emphasized the role of the Holy Spirit in the life of each believer and encouraged a rejection of legalism while supporting an austere, self-denying lifestyle.

Veneration as a Saint

Both the Roman Catholic Church and the Eastern Orthodox Church recognize Ambrose as a saint. Each year on December 7th, he is commemorated for his significant contributions to Christianity. Ambrose's life and teachings continue to inspire believers across different Christian traditions.

Why This Matters: Ambrose of Milan played a crucial role in defending orthodox Christianity against heretical teachings such as Arianism. His emphasis on the independence of the church from the state serves as a reminder that the church has a moral authority that can hold rulers accountable. Additionally, his contributions to church music and his mentorship of Augustine demonstrate the impact individuals can have in shaping the course of Christian history.

Think About It: How can we, as modern Christians, learn from Ambrose's teachings on the relationship between the church and the state? How might his emphasis on personal faith and reliance on the Holy Spirit influence our own spiritual lives?
