Some quotes from Archbishop Justin Welby:
“If we treat religiously-motivated violence solely as a security issue, or a political issue, then it will be incredibly difficult – probably impossible – to overcome it.
“A theological voice needs to be part of the response, and we should not be bashful in offering that.
“Until religious leaders stand up and take responsibility for the actions of those who do things in the name of their religion, we will see no resolution.” (Source)
