Five Solae of Reformation

The sermon series “Five Solae of the Reformation” explores the fundamental truths of the Christian faith that were rediscovered in the 16th century and remains the unwavering foundation of biblical theology today.

These five Latin principles concisely describe the way of salvation and the essence of the Christian life:

In this series, we examine each of these doctrines in depth to behold the majesty of God’s plan of redemption and find firm confidence in His Word.

Scripture Alone (Sola Scriptura)

13.07.2025 | Ivan Frolov | 2 Timothy 3:16-17

The conviction that the Bible serves as the sole supreme authority for faith and life rests on the doctrine of divine inspiration. Since God is the ultimate author, the biblical text possesses unique power to speak to hearts and govern conduct. Historical preservation and textual consistency demonstrate God's providence in keeping His Word intact across generations. The clarity of Scripture ensures that the essential message of salvation remains accessible to all who seek truth, regardless of their background. Every believer finds in these pages a sufficient guide for navigating the complexities of the modern world, as the written Word provides everything necessary for spiritual maturity and knowing God's will.

Christ Alone (Solus Christus)

24.08.2025 | Ivan Frolov | Hebrews 2:1-18

Jesus Christ occupies the central position in the redemptive plan as the only mediator between a holy God and fallen humanity. His unique ministry fulfills the roles of the perfect Prophet, who reveals ultimate truth; the ideal Priest, whose sacrificial death provides complete atonement; and the eternal King, who triumphs over death and governs His people with grace. The necessity of the incarnation arises from the demand for a representative who is both truly God and truly man. Through His finished work on the cross, the debt of sin is paid in full, offering an unshakable foundation of peace and eternal hope that requires no human additions or secondary mediators.

Faith Alone (Sola Fide)

14.09.2025 | Ivan Frolov | Romans 10:9-10

Justification before God occurs as a legal declaration where a sinner is pronounced righteous not based on personal merit, but through the imputation of Christ’s perfection. This 'great exchange' transfers human guilt to the Savior and His righteousness to the believer, received solely through the instrument of faith. Trusting in the finished work of Jesus serves as the only means of reconciliation, excluding all human effort or religious achievement from the ground of salvation. While good works necessarily follow as the natural fruit of a transformed heart, they contribute nothing to the legal status of the justified. This essential truth provides a deep and lasting peace, resting entirely on the object of faith rather than the strength of the believer’s own performance.

Grace Alone (Sola Gratia)

02.11.2025 | Ivan Frolov | Ephesians 2:1-10

Salvation originates entirely in the sovereign initiative of God, necessitated by the spiritual deadness of humanity. Since individuals are naturally incapable of initiating their own spiritual revival, grace acts as the decisive power that breathes life into the heart. This unmerited favor flows from the mercy of God rather than any perceived potential or merit in the recipient. Because the entire process of redemption is a divine gift, it eliminates all grounds for human boasting and religious arrogance. While grace transforms the life of the believer and leads to a walk of service, these good works function as the fruit of salvation rather than its condition. This doctrine provides an enduring assurance, as the security of the believer rests on God’s immeasurable riches.

Glory to God Alone (Soli Deo Gloria)

30.11.2025 | Ivan Frolov | Romans 11:36

The honor of the Creator stands as the ultimate goal of all existence, encompassing every aspect of creation and redemption. Since all things originate from God, are sustained through His providence, and find their final purpose in Him, no part of human achievement can claim independent glory. This principle transforms daily life into an act of worship, where even mundane tasks gain eternal significance when directed toward the exaltation of the Lord. True human joy is found not in self-promotion, but in finding complete satisfaction in God’s perfection. By acknowledging that every talent and blessing is a gift, the believer lives under a constant reminder that the highest meaning of life consists in reflecting the splendor of the Savior in everything.
