I've had opportunity to interact and observe PeterJens a bit longer than you have, and take note:
My objection to hyper-grace is not that people themselves accept Christs love, know His forgiveness,
walk in the Spirit, have love and faith growing in their hearts. This is beautiful.
It is when a person says, I am not following OSAS, or I see beauty in the law, and desire to walk
righteously and in purity, they are labelled legalists and deniers of the gospel that I have a problem.
To say reading the law or reading the sermon on the mount bring condemnation and is evil, it a
big spiritual problem. To then build on this and create a mystical gnostic theology, is going into
heresy.
There is always a broad spectrum of expressions and aspirations within the christian body.
Now where ever you sit on this spectrum, you are probably happy with it, and if I come across
as an enemy, then I am evil, slanderous and wrong, but if I am closer to your position I am just
speaking the truth in love.
This illustrates how belief gets translated into sin, which is always a dangerous road to walk.
The other problem is changing the meaning of concepts and ideas, means you can be very happy
with a statement, but mean the opposite of another believer reading the same statement but seeing
something very different.
My answer to this is to reduce relationship and complexity to that of a child, and laying things out
simply. If people bring love and life amen, if they miss-behave and do evil acts, then that needs
to be confronted.
Now what I am accused of is expressing my point of view. If you think this is sin, then I have a problem
with your sense of morality, and I would describe this as hyper-legalism.
Another indication of hyper-legalism is saying fear is sin, or doing things for yourself is sin, or setting
your own goals and failing to meet them is sin, or anything that is not "christian" is sin. These would
fall into OCD psychological disorders, where people cannot distinguish between good, loving sincere
behaviour and real sin, or harmful behaviour to others, oneself and God.
