Answer:
The correct answer to the question: Which literary technique does this line use, would be, irony.
Explanation:
Irony is literally described as the almost laughable difference between what is actually happening in a text, and what is expected to happen. When the writer of this line speaks an old Baptist church, the expectation from the reader is of an atmosphere of peace and quiet, of tranquility, but never something related to violence, or aggression. But what actually happens is quite a different thing. When the line later says: "no need to run" in reference to the church, you feel the irony and know that something completely opposite happened here. That is why the answer is irony.
