Defending yourself (or others) by seeking revenge for something done to you (or others).
Ex. 1- Don: Jack Bauer and Batman just went on a mission to find and apprehend the crazy terrorist who bombed Gotham Los Angeles Plaza.
Bill: Yeah, they both seek defengeance for what happened. As long as the terrorist are out there we aren't safe.
Ex. 2- Whenever a member of a gang sees someone from a rival gang, he's obliged to defengeance himself. He must defend himself from a possible attack (whether immediate or in the future) by seeking vengeance on the rival gang member for all the pain the rival gang has cause him. It's a never ending cycle.
church hurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
Now that I am an adult I am beginning to heal from the church hurt that was inflicted on me as a child.
