Becoming a pastor is not something we earn through getting a formal education; it is a spiritual gifting and calling that we do or do not have (Ephesians 4:11-12). There are those with the spiritual gift of shepherding and teaching who may not ever get a formal Bible education, and that by no means disqualifies them from the pastorate, especially if they fit the godly character and other criteria needed as recorded in 1 Timothy 3:1-7 and Titus 1:9. With that being said, there are certainly benefits to getting a formal education in the Bible, mainly because it gives pastors a set aside period of time and conducive environment to deeply study and understand God’s Word and grow spiritually (2 Timothy 2:15). At the same time, deeply researching and studying the teachings from God’s Word can be achieved without a formal education.
Some church traditions include formal requirements regarding Bible education for those who serve as pastors, however, getting a degree in Bible is not a biblical mandate. Moreover, there are many forms of Bible education, and not all training is formal training. For example, in many parts of the world, the majority of people in a village may be illiterate. Bible training in this context is still important but may take a much different form than in a culture with a high level of formal education. Instead of writing papers and reading books, the focus is often on memorizing Scripture, biblical sermons, and interaction with other church leaders.
Additionally, not every person has the opportunity for formal Bible education. Some very gifted pastors have no formal Bible education yet are very effective due to a combination of God's gifting, diligent self-study, and informal education. The renowned British pastor Charles Spurgeon lacked formal Bible education yet read six books each week in addition to constantly reading the Bible. God used him to lead one of the largest churches of the nineteenth century in London despite his lack of formal Bible education.
In conclusion, while formal Bible education is not always possible, growing in biblical wisdom should be a high priority for every church leader and it should be encouraged whenever possible for those who seek to lead in Christian ministry.
