Does the LCMS Need to Change? Lutheran Tradition vs. Innovation | Seth Kasten | Episode 149

Summary

Seth Kasten’s Path to Lutheranism

Seth Kasten says he grew up in a broadly non-denominational Protestant setting, attending churches from several traditions. In college, conversations with Lutheran friends and reading biblical passages about baptism and the Lord’s Supper led him to find Lutheran teaching persuasive. He later became involved at Zion Evangelical Lutheran Church in Detroit, whose formal liturgy differed sharply from the evangelical megachurch style he had known.

What “Scholastic Lutherans” Does

Kasten’s YouTube channel aims to make historical Lutheran theology accessible to ordinary Christians. As he describes it, Lutheran scholasticism combines theology with classical philosophy—especially Aristotelian thought—and developed across the medieval, Renaissance, Reformation, and early modern periods. His focus is mainly on Lutheran theology from the Reformation through roughly 1750.

Kasten argues that Lutheranism is both biblical and catholic, in the sense of belonging to the church across times and places. Scripture is its foundation; church tradition and philosophy can support the study of Scripture but should not outrank it. Scholastic precision is especially useful for educating pastors and clarifying doctrine. Its influence also reached congregational life through liturgy, music, catechesis, and teaching about Christians’ everyday vocations.

Prayer Practices and Spiritual Discipline

Kasten explains the breviary, or “prayer of the hours,” as a structured pattern of prayer at set times of day, centered especially on the Psalms. He traces the practice to biblical examples and describes how it developed in the life of the church. A full historical breviary can be complex and may suit monastic or cathedral settings better than everyday use; modern Lutheran resources offer simpler forms.

Resources mentioned include:

• Treasury of Daily Prayer: A simplified guide to daily prayer offices and readings.
• Prayer Book of the Brotherhood: A more traditional option using Gregorian notation and the King James Version.
• Oremus: A middle ground, with modern musical notation and a more historically developed structure than Treasury of Daily Prayer.

Kasten and host Zach Zehnder discuss whether Lutherans can become so wary of “works righteousness” or pietism that they neglect spiritual discipline and practical guidance for Christian living. Kasten says grace must remain central, but he also believes churches should encourage good works, address specific sins, and help people grow in sanctification. Saying only “there is grace for you” may be doctrinally correct yet fail to answer someone asking how to resist a particular sin.

Practical approaches Kasten recommends:

• Use a regular prayer practice, drawing on a prayer book or a simplified form of the daily offices.
• Try daily self-examination: Review the day using the Ten Commandments, virtues and vices, or the seven deadly sins. Note where you fell short and identify what needs prayer and attention.
• Set specific goals for growth based on that reflection, rather than treating self-examination as a way to earn God’s favor.
• Seek pastoral care and the means of grace, including confession and the church’s proclamation of forgiveness, when burdened by sin.
• Use sound devotional and theological resources for practical guidance. Kasten recommends Johann Gerhard’s Schola Pietatis and Johann Arndt’s True Christianity. He also describes the Memento program as a helpful source of daily reflections and shortened prayer offices.

Confessions, Communion, and “Adiaphora”

The discussion considers whether Lutheran confessions describe historical practice or prescribe what churches must do. Kasten says the distinction does not always change the basic point: the confessions define Lutheran teaching and practice, but particular statements must be read in their historical context. For example, the Augsburg Confession’s defense of the Mass responds to accusations that Lutherans had abolished it. Kasten cautions against treating every detail in that defense as a universal rule for every congregation.

On weekly communion, Kasten says the confessions’ historical description of frequent services should encourage churches to provide the Word and Sacrament regularly. However, he does not consider weekly communion a specific requirement for every LCMS congregation. He argues that Scripture calls Christians to the sacraments but does not prescribe a particular weekly schedule. Zehnder reports survey results from 3,068 LCMS respondents: 66% said their church celebrated communion weekly, and 98.8% said it was offered at least twice a month.

Kasten distinguishes between freedom at the congregational level and decisions made by the church body as a whole. “Adiaphora” refers to matters neither commanded nor forbidden by Scripture. Such practices may be changed, but Kasten says historical ceremonies should not be discarded without good reason. Changes can also become problematic if they create division, disrupt church peace, contradict Scripture, or obscure a church’s confession.

He gives the historical example of Lutherans using white wine in response to a dispute with Reformed Christians: a practice that was otherwise indifferent became a public way to distinguish their teaching.

Tradition, Innovation, and the Church’s Future

Zehnder raises the tension between preserving inherited worship and innovating to reach people. Kasten argues that innovation is valuable but generally should happen around the liturgy rather than by casually replacing it. He sees the liturgy as a shared, historic expression of the church’s confession. He cites biblical calls to remember and respect what has been handed down, while also acknowledging that traditions are not infallible and may need adaptation.

Examples of innovation that can complement tradition include Bible classes, podcasts, apps, and presenting prayer resources in formats people can use today. Kasten’s position is that the church needs both people who preserve its inheritance and people who find effective ways to communicate and teach it.

Asked what Lutheranism most needs, Kasten emphasizes well-catechized children. He considers parents and household leaders central to passing on the faith; pastors and church programs cannot fully replace teaching at home.
