Truth is important; and coming to the knowledge of the truth is for us the heart of the Father.
He wants us all to speak the same thing (1 Corinthians 1:10, Philippians 2:2-3): but for that to happen we must all believe the same thing.
For that to happen we need to have the opportunity to hash out our doctrinal differences.
Even nonessential issues are important, when it comes down to it (see Luke 16:10).
PS I find it interesting that someone with the moniker of
@Truth would admonish us to seek unity at the expense of truth! (We ought to pick monikers that fit our general direction of posting.)
