Check out the writings of your own church fathers. As time passes you will find them deviating more and more from the scriptures, such a veneration of Mary, asigning people sainthood after then are dear and the false doctrine of Apostolic sucession to name a few.
Share a source, not a vague reference to something like "early church writings."
The Catholic Church is an ancient, large Church. Being ambiguous makes me think you're simply tossing out an accusation you are unable to back up.
Apostolic succession is taught in Scripture. Who do you think appointed the overseers (= bishops). The Apostles did!
But more to the point, one of the most vehement defenders of Apostolic succession was Irenaeus of Lyons, who was a disciple of Polycarp, who was a disciple of John, who was a disciple of Jesus. So three generations (and about 150 years) removed from the "beloved disciple" reclining on Jesus' breast, the true message had already been lost? And you think you've recovered it 2000 years later?
Doubtful, friend. Doubtful.
