While perhaps I would be speaking out of line, and I am by no means a very experienced christian - being that the only thread I have made is also in the 'convert issues' forum - it may not be too dishonest to accept and be open about the fact that you are Orthodox, while attending a different church. The nearest Orthodox space to me is some four hour drive, to a Russian Orthodox parish that congregates occasionally in the underground lockers of a catholic church. I attend a catholic church - though, not the mass, by heavenly mercy - to pray and make devotions to the icons, and the like. And there is much to be admired in those churches - the Stations of the Cross and St. Ignatius, and so on. And it is a personal journey for me, also - I am a 'catholic' in this country - that means, I identify as Irish, and not British - and 'Catholics' in this country are persecuted. And my town is 95% 'Protestant' (which means to identify as British, and support the Imperial occupation). There is only one catholic church in this town and it is regularly attacked and having its windows broken and its altars desecrated, and blasphemes written, and more than once bombed and lit aflame. And it is dangerous for me to enter this church, lest I be seen by the wrong people.
So for me it is a holy journey to cross that threshold! Though it is not my Church, merely attending is an act of tremendous devotion to God and to God's Ireland, and against the forces of Imperial evil which wish to distinguish that faith, whether I have that faith or not. And perhaps that is some holy journey (a song we have here goes 'Some say the devil is dead, and buried in Kilarny - I say he rose again, and joined the British Army' haw haw haw).
While it may not be such a crucial thing for you, all I am saying is that I absolutely understand the desire to be in a holy place. And so you should go to that holy place, and pray there, and prostrate before the altars, and if you want get to know the congregation. And there is a tradition in Lutheranism to be proud of - that legend Kierkegaard is an eternal inspiration to me, and the reluctant anti-semite Luther is a hilarious, though completely deplorable, character. So on... It is something that has existed here in our old tangling tradition and it is something to behold. So you may go there and feel holy. But avoid the sermons, or whatever, if they do not please you (they would not please me), and call that priest you are in correspondence with as you like, and enjoy meals of wine and bread, and whenever the opportunity opens to you, make the pilgrimage to the altars of the Orthodox Church, and that would be a tremendous expression of your Will, and the Will of God, surely!
Good luck, etc. and thanks for letting me babble for so long about things I know little about, ahahaha
