Why is holding to apostolic traditions important for Christians?

For Christians, adhering to apostolic traditions is crucial in preserving the teachings and practices that reflect the authenticity of the faith as delivered by the apostles. Paul's exhortation in 2 Thessalonians 2:15 underscores the importance of these teachings in combating false doctrines that arise in apostate religions. By holding fast to what the apostles introduced, Christians establish themselves in the truth, ensuring their lives and worship remain centered in the guidance of God's Word. This integrity is necessary for spiritual growth, unity, and the proclamation of the Gospel.
