What’s the difference between a Bible college and a theological college?

In Australia, a Bible College has traditionally helped people to understand the Bible by teaching through the books of the Bible. A Theological College has traditionally included much more detailed study (languages, discourse analysis, etc.) of the text and training in thinking theologically – how to put the whole Bible together and think through the shape of ministry in line with that. The course at a theological college is usually designed (carefully and intentionally) to equip people for a full-time teaching ministry, giving them all they can to prepare people for that, while the course at a Bible College is more designed (just as carefully and intentionally) to help all Christians know their Bible better. That distinction has become a little blurred over the past few decades as Bible colleges moved into offering degree programs, which until recently had very largely been something only theological colleges did.
