The early church and the New Testament letters

Acts (sometimes called ‘the Acts of the Apostles’) is the sequel to Luke’s Gospel. It begins in Jerusalem, with the gift of the Spirit at Pentecost, and ends in Rome — the political centre of the empire. In between, the gospel spreads across cultures, ethnicities and boundaries.

It’s a story of bold preaching and quiet community, of miracles and arguments, of expansion and persecution. Acts shows that the early church wasn’t a smooth machine — it was a Spirit-led movement working things out as it went.

Most of the rest of the New Testament is letters — sometimes called epistles. Many are associated with Paul, written to churches he had founded or hoped to visit. Others come from leaders like Peter, John and James, and were written to wider audiences.

These letters are not theological textbooks. They are real letters into real situations: a divided church, a struggling friend, a community wondering how to live faithfully under pressure. Knowing this changes how we read them.

When we say a letter is ‘occasional’, we mean it was written for a particular occasion. The author isn’t writing a systematic statement of everything they believe. They are addressing specific issues — sometimes correcting, sometimes encouraging, sometimes simply greeting.

This is why a good study Bible or short commentary can be so helpful. Even a brief introduction telling you who is writing, who is being written to, and what was going on, can transform a difficult passage into a meaningful one.

Three questions take you a long way: Who is writing? Who is being written to? What situation is being addressed? Once you’ve answered these, the surface of the letter usually becomes much clearer.

Then ask: what does this passage assume about God, about people and about life together? And finally: what might this still invite from us today, in our different setting?
