I believe in absolute truth. However, the only absolute truth we can ever have personally in this life time is that we will never have anything but an inkling of absolute truth. The Apostle Paul told us, and so we should not be surprised, that until the day comes when we all reach the fullness of Christ, we most certainly will be tossed too and fro by every wind of doctrine and we are at risk of being manipulated by the cunning manipulations of those who have a hidden or even unknown agenda.
Get used to it; and hang on. We are not there yet and all conclusions are for the moment, tentative to an unknown degree.
