In talking to many modernist Christians it seems that their math does not add up. Often they add man made philosophies to the Truth of Scripture. Never do they realize to have Absolute truth means then there is truth that is lesser... meaning that they created an issue that denies scripture's teaching that Truth is the Person of Jesus and not some abstract thought. If Truth is diminished by adding to it, then I see it is the modernist who then diminishes truth as a whole.
One cannot have a lesser truth as the Bible simply calls that a lie. Truth is the Person of Jesus and if we add to that we only come to wrong conclusions and according to scripture it just will not add up. Believing a lie even dressed as truth is still believing a lie.
