Something that is sometimes difficult for me while reading is grasping the context. This is especially important when reading older works like the Reformers. I don’t have the context of who they are responding to or why. Words are often older and unused today, or worse, have different meanings today than they did when they were written. The built in dictionaries are usually of little help because they are written for a modern context. Beyond that, phrases usually don’t have any definitions and taking time to figure it out, I lose the line of argumentation, if I understood it at all.
I have several ideas here, but am curious if others also have this issue.
