You can also read “Orthodoxy” by G. K. Chesterton. Written while he was Anglican, it describes what orthodoxy is, for Anglicans, Catholics, Christians in general. Orthodox Catholics aren’t necessarily “conservative”. Orthodox Catholics support Vatican II, which preserved doctrine but applied the Church’s pastoral practice to a very different world. Not all changes are “upheavals”. Some development occurs, guided by God, though a single human agency.
The difference between Episcopal and RC is that the RC has (besides Scripture and Tradition) the Magisterium, which orthodox Catholics are obedient to. (There are other Catholics, mostly liberal and some conservative, not obedient to it). The Episcopal Church does not have a magisterium. They rely only on Scripture and Tradition. Episcopalians/Anglicans have leaders, but neither they, nor other Christians, attribute anything like Magisterium to them. The leaders themselves don’t claim it.
But I urge you to read “Orthodoxy”. Regardless of your position or denomination, you find the (Anglican) Chesterton defines the issues involved.
