I was raised in the Roman Catholic Church and converted to the Eastern Orthodox Church as an adult after many years of searching and hesitation. I am Orthodox because it lines up with the teachings of Jesus, I joined because I agree with their teachings more than I do any other teaching of the Gospel.
Also, I like the challenge of living the Orthodox life. Certainly, I fail, but out of all the teachings, the Eastern Orthodox is by far the toughest to live in this world.
Orthodoxy-Christianity, only tougher.
