I agree with you. You never flat out said that we cannot completely know the truth.
What you have said is that The Truth is out there and that some people have some of The Truth but not all of The Truth.
In a nut shell: Marymog may have The Truth about ABC and be wrong about XYZ which means she has only part of The Truth. But Amadeus has The Truth about XYZ but be wrong about ABC. The Catholic Church has the truth about DEF and
@brakelite has The Truth about HIJ but is wrong about KLM and ABC. Based on your theory that means The
FULL Truth is out there and we know it, however, not one person (our group) owns The Truth.
The only dilemma with your belief is that if everyone has a portion of The Truth and
no one can agree on what portion is true that means we really can't completely KNOW The Truth. Sooooo in effect
you do believe that we cannot completely know The Truth.
