Many programs require you to learn New Testament Greek or Biblical Hebrew. You will find that knowing it gives you new insights into the Bible through being able to understand the original wording. You also will understand some of the thinking of early church scholars. In the Roman Catholic Church, Latin is very important for the same reasons.

You probably will want to study at a college or seminary affiliated with your church, or you might consider one that has generally compatible beliefs. Your clergyperson can give you guidance on this matter.
