I think you are a little confused.
Actually, I think keats5 is right. To be a "moderate" would mean moderation, a little this, a little that. Which is totally against loving the Lord with all your heart, soul, mind and strength.
Its the Christians "in" the world who don't take seriously or literally the Bible. The ones who rationalize Gods word.They are the moderates. A little faith, a little rationale, a little rightiousness here, a little secularism there.
Would you tell your wife (or husband), "I love you, but in moderation" ?
