Since i've lost faith in Protestantism and have concluded Eastern Orthodoxy to be the most authentic form of Christianity in the present age, i've been considering attending the services of a Russian Orthodox church i've discovered being active in my city. For the last couple of months i've been reading many books about early Orthodox theology and have listened to many lectures on the subject. However, having no church-going experience outside of Protestant Sunday services, but simultaneously not wanting to stand out, i'd like to ask; what is expected of a person attending an Orthodox service that wants to completely blend in with the rest of the worshippers?
