@Nufan you say a lot of true things but others like Daisy say a lot of true things too.
Especially knowing that even the apostles themselves had different personalities which is what Daisy said.
I realize that you want to show people a new path, but people are not convinced sometimes even with a miracle. Nevermind if you try to talk to them in real life or even the internet.
What's important is to take what's edifying for you in every group or church, including the internet.
In this internet community, i also also learned edifying messages from a few members while not arguing about the rest. Because what is there to gain by arguing besides a waste of time?
Some members are interesting to talk to and others are 'lone wolfs' like you said.
But despite all of this, you have to respect everyone's journey and free-will, including the Calvinists.
Because sometimes even a Calvinist or a Mormon says something that's interesting to listen to and learn something.
This is also tied to the concept of forgiveness and grace and humility which are points that you mentioned earlier and in the orthodox church are tied to the concept of Salvation which in itself is non-jugmental.
This is why you need to let people walk their path.
From what i understand, the Catholic Church has left a bad taste in a lot of people's mouths in the West so they have a 'hate' for anything Catholic so you have to put that into perspective as well.
What's important is for you to stay happy and in peace in your path and i'm happy you chose the Orthodox Church which has been continuing its message in an unbroken chain since the time of the apostles.
Also, look what they found :

Christianity spread in the Germany region at around year 250!
These were the first or second generation of the followers of the apostles and Christ themselves (they mention Titus in there) who spread Christianity (before there was even a Creed or a NT Bible)
So it's important to know history and i value that myself, but you also need to allow for free will. People learn by doing a lot of times, not by hearing.
