Dan, not quite. The Catholic Church alone has the fullness of Christ's teaching. It alone can trace its roots directly back to Christ.
Protestantism didn't come along until the 16th century, started by rogue Catholics who rejected parts of the faith.
You have no basis to judge what the Catholic Church teaches other than your own personal interpretation of things, or the personal interpretation of some other mere human being without Divine authority.
See 2 Peter 1:20-21, that says, "Know this first of all, that there is no prophecy of scripture that is a matter of personal interpretation,
for no prophecy ever came through human will; but rather human beings moved by the Holy Spirit spoke under the influence of God."
And, yet, personal interpretation of Scipture is one of the founding principles of Protestantism. That's why there are literally tens of thousands of man-made, doctrinally contradicting denominations (and counting). Everyone is his/her own Pope, interpreting Scripture personally.
Unless, of course, you're claiming that Jesus, Himself, came back and informed you that what the Catholic Church is teaching is wrong? Or an angel?
