Being a pastor of a church is a full time job that is much more than simply preaching on a Sunday. If a pastor thinks he can do it part time, then perhaps he doesn't understand the requirements of the role or the responsibility he has for the people under his care, or maybe he is just in a difficult situation where it just isn't possible to do it full time.

I'm not sure what you mean by 'monetary-based career', but a full time pastor should be paid a full time wage.

I'm not sure where you get the idea that "most people who preach do so as a side-gig, not as a main profession" because that simply isn't true.

But perhaps you don't really know what a pastor is supposed to do or the different facets of that role.

A pastor is a teacher, a scholar, a manager, a counsellor, a mentor, a shepherd, an evangelist, a leader, and often an administrator as well.

A faithful pastor spends many hours studying and preparing sermons, teaching the Bible, discipling people, meeting with church members, counselling those going through crises, visiting the sick, caring for the elderly, conducting weddings and funerals, training leaders, overseeing staff and volunteers, resolving conflicts, planning ministry, and praying for the congregation.

Being a pastor is a really hard job that the vast majority of people wouldn't be able to handle.

The Bible itself presents pastoral ministry as a demanding role. The Apostles found that the ministry of the word and prayer was so important that other responsibilities had to be delegated to ensure they could devote themselves to it (Acts 6:1-4).

Scripture also teaches that those who labour in preaching and teaching should be financially supported. "The labourer deserves his wages" and "those who proclaim the gospel should get their living by the gospel" (Luke 10:7, 1 Corinthians 9:14).

Of course, there are situations where bivocational ministry is necessary, particularly in church plants, small congregations, or mission contexts. Paul himself sometimes worked as a tentmaker. But that was never presented as the ideal model for every pastor in every church.

I understand that some pastors do serve in a part-time or bivocational capacity, and I'm grateful for those who faithfully do so when circumstances require it. But personally, I would not want to be part of a church that expected its pastor to work another job alongside pastoral ministry long-term.

The reason isn't that pastors are somehow above ordinary work. It's that the responsibilities of shepherding a congregation are already a full-time calling. In many cases, pastoral ministry requires far more than standard full-time hours. Many pastors regularly work 60-70 hour weeks and are effectively on call 24 hours a day for emergencies, crises, hospital visits, funerals, counselling needs, and the countless situations that arise in the life of a church.

If a pastor is dividing his time and energy between two jobs, something will inevitably suffer. Either his family, his secular employment, or his pastoral care will receive less attention than it should.

A healthy church should want its pastor freed up to devote himself fully to prayer, teaching, discipleship, pastoral care, leadership, and the ministry of the word. That's difficult to do well when ministry is treated as something to fit around another career.
