The Roman Catholics believe that we inherit original sin from Adam and Eve. The Orthodox Church believes that, while the sin of Adam and Eve caused the "Fallen nature" of the world, we are no longer guilty of their sin, because of Jesus Christ (the New Adam) and the Holy Virgin Mary (the New Eve) have saved us from sins. The Virgin Mary's role is by giving birth to the Saviour and by praying to God on our behalf. Christ's role as our Saviour is by cleansing us of our sins (initially via baptism and also via confession) through His death and glorious resurrection on the Cross.
This was confirmed by Jesus in The Bible when His disciples asked Him "who sinned, this man or his parents, that he was born blind?" Jesus ed, "Neither this man nor his parents sinned, but that the works of God should be revealed in him." (John 9:2-3).
We are responsible for our own sins, not those of others, and we will all be judged according to our individual works at the Second Coming of Christ. (2Timothy 4:1, Revelation 20:12, 22:12).

I believe their are about 75 books in the Eastern Orthodox bible. Below is a link to Wikipedia. org that shows the different books, their names, and whether or not they are from the Jewish, Protestant, Catholic, and/or Eastern Orthodox traditions (they also list the original language it was written in).
The Eastern Orthodox Church uses the Bible. The books in their Canon are slightly different than that of the Roman Catholic, but they also use 3 Maccabees, Psalm 151, and 1 Esdras.
The oriental orthodox,eastern orthodox and roman catholic churches all started when various apostles spread mainly the middle east and eastern Europe. Soon the churches started to split the oriental orthodox then eastern orthodox and catholics together. Its hard to say when oriental orthodox started because it consists of several apostolic churches in communion which each other all founded at different times by different apostles

The Eastern Orthodox religions
That's a long an complicated question. The short answer is the Roman Catholic Church celebrates most holidays on the Western Calendar while the Eastern Orthodox use a slightly different calendar known as the Eastern Calendar. Some years the dates are the same and others they are different. The Roman Catholic Church structure is similar to the Eastern Orthodox. However, the Eastern Orthodox setup a church in each country (generally, America being one notable exception) whereas the Roman Catholics have a world wide structure.
There are Eastern or Byzantine Rite Catholics but they are in full union with Rome as opposed to the Eastern Orthodox Churches which are not. There was a brief period in the 20th century, when a separate Orthodox Church broke away from the Eastern Orthodox Church in America and formed the America Orthodox Catholic Church. But it was yet another splinter of an already splintered Church. orthodox (small "O") means right belief, and thus is synonymous with Catholic. Now, there is also an Orthodox Catholic Church of America, also not in Communion with the Catholic Church. . You may read about the American Orthodox Catholic Church at the links below.
