I can say that the closest denomination to Orthodoxy is Catholicism. But again, with Anglicans we have some similarities. Though again, I disagree with many teachings, I feel close to them because they respect tradition and there are some liturgical similarities with the Orthodox. There are more similarities between Orthodox and Anglicans than Orthodox and Protestants, as far as the worship and the tradition is concerned.
I generally can say that I feel close to all Christians, no matter if I disagree with their theology. We are all children of the same God.
God bless you!
