Today is the last day we (Orthodox Christians) proclaim our Paschal greeting, Christ is Risen! This is considered a peaceful salutation and we say this for about 40 days after our celebration of the Resurrection ...
Orthodoxy is perplexing and it seems startling at first but as time goes by (and those who have converted to Orthodoxy in their adult life will affirm this) the principles and lifestyle and "T"heology become less and less so ... it all "feels" like "home" and a sublte and gentle inner joy takes over and we are all cheerful people who love God, we love life and we love the people around us.
I use those words intentionally ... there is plenty of room for scholastic analysis and debate but to the Orthodox it is not about academic proofs but it is about a relationship and connection to Christ ... and He feels more and more like home and His love gradually draws you into your true home, the Kingdom of God.
This was the message of the Gospel in the early church - a reconciliation of man with God but due to a number of complicated historical factors the message was modified by certain men who wanted to develop and start a new church structure of their own liking.
This breaking away has been the deep rooted cause of many men to have been hurt by the "distorted" message of the Bible they have been taught and so many human beings struggle to "like" God, they blame God and hate God and to justify their position are negative to the true message when it comes there way ... He waits for them though, like the Father waited for the Prodigal Son (and upon return of the Prodigal Son, the Father did not give him lectures or get angry but rather threw a party).
The Orthodox theology and worship are different to the experiences of Christian theology you describe and have experienced ... these differences are not apparent through a forum and thus why evangelisation in a forum is also near to impossible for that reason.
So, in essence, I do not disagree with you ... many things cannot be proven and by the same token those same things cannot be disproven ...
So, I don't "know it because I know it because I know it" ...
I know "IT" because I have lived it and experienced it ... and the outcomes of this experience give meaning to life and purpose and the evidence is in the restoration of my entire being.
