Are differences in Doctrine alright to ignore? Why is just a little leaven dangerous? Do circumcision and uncircumcision have the exact same effect on salvation? Will preaching the Gospel of Christ alone always cause anger in those that have not been taught by the Spirit? Is the fact that Christ accomplished justification, redemption, reconciliation and sanctification for His chosen ones at the cross open to interpretation?
