Really? Check #13. It is a gross lie of its own fabrication.
Your interpretation of Scripture is not the Church’s and it is yours that is the innovation. Both purgatory and veneration of the Theotokos are thoroughly Biblical. Outside of Scripture, clear Marianisn appears by the mid-2nd Century, long preceding the canonization of the New Testament. Purgatory not only appeals to common sense and what we understand about God, but is in Scripture at 1 Corinthians 3:15 (that pesky Paul again). Also Jesus Parable starting at Matthew 18:22.
