Orthodoxy is false and isn't much different than Catholicism. They split in 1054 so they could fully immerse babies when baptizing them but you're not supposed to get baptized until after you believe on the Lord Jesus, as it is an outward expression of your faith to show the world. Orthodox churches do not teach that salvation is by faith alone and they worship graven images which God said not to do.

The devil has been working hard at hiding the truth and simplicity of the gospel with these various false churches. The word "gospel" means "good news" and the fact that going to heaven when we die because we simply have believed in the Lord Christ Jesus is indeed, good news.
