The goal of Orthodox Christianity is theosis, which is how we understand salvation. That is, we become partakers of the divine nature and in cooperating and abiding with the divine uncreated energy of God that fills all things, we are united to divinity. This is complete after our time in this world. In this world we become co-workers with God as living icons of The Truth. Our God is The Truth. That being the case, a big part of our discipline has to do with freeing ourselves of prelest, or delusion. We recognize that the pure in heart see God, and so our discipline involves the cleansing of the nous of the influences and passions that lead us into delusion or obscure the Image of God in us.I am sure you can at least see here that we do have some in common. There is also much that is different.Reincarnation simply does not fit into our eschatology, as there is no need for multiple lives. Everything is revealed as it is in eternity, and the very same light of Truth that is paradise to those who abided in The Truth is the fiery torment that afflicts those who have lived a life in defiance of The Truth.We would also say that the idea that one can save themselves is prelest, because we understand that The Truth is what saves and liberates, not our own will. We see ourselves as having a personal relationship with The Truth, and so we say that The Truth is what cleanses us, not our own efforts. That said, we still play a part in this through what we call synergy. That is, cooperation with this divine energy. All Orthodox Christians are called to be ascetics.Though there are 30,000+ nominally Christian denominations, the oldest creeds of the church state a belief in "One, Holy, Catholic, and Apostolic Church". That very Church is around today in the form of The Orthodox Catholic Church. What I am really saying here is that of these 30,000+ nominally Christian churches, there is only one Church that can legitimately be called Christian and Orthodox, and this is something that is easily confirmed in studying the history of the church.
The fact that we have 30,000 denominations of Christian is proof the early Orthodox Church was found wanting and left behind. Christianity had to evolve because the Old Testament teachings did not work for the Jews. Even Jesus who followed judaism was crucified. So the closer you are to the source like Orthodoxy the less relevant you are to modern Christianity.
Paul said to the faithful the promise was not kept. The believers are still in their graves waiting to be resurrected. Hindus dont have that problem. Reincarnation gets them back on their feet and working on their next life cycle. Some like Buddha even break through in their first attempt. No such hope for Christians. Their resurrection is dependent on Jesus returning. From dust to dust was the original Christian curse, remember?
