I'm probably the last guy you should listen to on this subject but in my humble opinion to think, or perhaps better said imagine
, such a thing sounds beautiful to me! To practically seek, or realistically consider it, might make you very radical indeed!
In a way I think you are touching upon a core principle of Christianity; 'To love your neighbor as yourself'
I am not saying we should embrace beliefs, dogmas, theologies or even traditions & cultures that we do not agree with of course. How can anyone turn away from the love for Truth and Understanding they believe they have found in such? To live in Christ however, should we not constantly remind ourselves to not judge or look down upon others for seeking God in their own way? Even if we suspect that way is false. Take my being on this site as an example; there are issues of Orthodoxy I either do not understand, or do not hold as truth in my faith, that most others on here would view as my being wrong. If I was not accepted here, felt constantly judged, or looked down upon I would either not be here (I consider it a privilege and am humbled to take part by the by) or I would be in conflict with others on a human/worldly level. Perhaps even rejecting Orthodoxy all together. How could I possibly then see or have any misunderstandings revealled to me in that situation? Conflict rarely if ever leads to correction - but cannot God's love, understanding, acceptance, etc. reveal all that is Truth? idk Just thinking out loud I guess.
What does weigh heavily on my heart and mind at times is not unity but division. I accept and understand the profound significance of difference amongst Christian sects. That should not be overlooked in my opinion. However those differences, seems to me anyway, pale in comparison to our shared love and belief in God. I sometimes worry that the evil one uses those differences against us to divide, and hide the Truth within the conflict of our human nature.
I suppose that might make me a little radical too?
Lord have mercy on us all!
