The Church is a bulwark of the truth (1 Tim 3:15)

1 Timothy is one of the Pauline Epistles that is closely associated with 2 Timothy and Titus. These letters are often called the "pastoral epistles" because they give instruction concerning pastoral issues in congregations. The letter is addressed to Paul's companion Timothy. The first chapter recalls that Paul was the foremost of sinners for persecuting the church, but affirms that Christ came to save sinners. The body of the letter deals with questions of order in the church. The author lists the qualities of good bishops (or "elders") and deacons, deals with the position of widows. The church is called the household of God and bulwark of truth. The letter concludes by calling upon Timothy to "fight the good fight of faith" considering the example of Jesus who remained firm even in the presence of Pilate.

1 Tim 1:12-17 - Foremost of sinners
1 Tim 6:11-16 - Fight the good fight
