Presumption of theological innocence

Speaking of the 9th Commandment, Professor John Frame says:

We have the responsibility to put the best construction on other people's words and behavior, unless there is cogent witness to the contrary, what the Bible calls "two or three witnesses." That means we are to give one another the benefit of the doubt, on the principle of "innocent until proved guilty." I suspect that adherence to this principle would substantially reduce the amount of theological controversy.
