Ok so I've been giving this some thought while at work. I have enjoyed the comments that people have left and they have helped shape what I am about to say. These thoughts are not the final word (obviously not to all of you but I also mean in my own thoughts). So here is what I'm thinking...
What I am struck by is this, legalism and liberalism are actually closely related. They are like estranged sisters who refuse to talk to one another. Let me show the similarity.
First the legalist - they believe that God meant for His law to be obeyed and they feel that the way to be spiritual is to obey all of God's commands. God rewards those who obey. They cite many verse such as, "The Lord loves obedience rather than sacrifice" and you've heard the rest. Anyone who does not follow God's law as they see it is not a 'good' Christian. Hence a works based system.
Next the liberal - they believe that Jesus came to be an example to the world. Jesus' objective was to enact social change through disrupting the status quo (thanks for the quote Ando). We are to follow Jesus' example in order to be His disciples. The point is not whether or not Jesus walked on the water but that He fed people and healed the sick (they would question the miraculous nature but applaud the goodness of Jesus' work). So we should continue His good work by taking care of the needed, etc. Also a works based system!
I think we all know the differences between a legalist and liberal. We may find ourselves interacting with legalists because they would believe much the same way as we do about the Scripture, Jesus, miracles, etc. We would not want to associate with the liberal because they deny much of what we believe about these things. However, I'm shocked to think that legalists maybe so closely related to liberals. Could they both really be works based systems? Tell me what you guys think.
