Christianity is not a thing nor is it a person, as such it can be neither wrong nor right.
Christianity is a belief that encourages us to follow the teachings of Jesus to best of our ability.
Most Christians have a system of beliefs that are embedded in their Dogma.
There is no one size fits all variety of Christianity.
There is no True Christianity, sinless Christianity, or universal Christianity.
There is no single version of the Bible, There is no single interpretation of the Bible. there is not even the same number of books in every Bible.
It is not even important that every thing we believe and is contained in the Christian Tradition and Bible, are are the exact word of God or with out error.
God loves us anyway.
