When the Catholic Church appears to
teach "new doctrines" about Mary, it is often a statement of truth against some current
errors or a clarification of truths
that have always been taught and believed by Christians through the centuries.
The Church believes that handing on
these truths participates
in the admonition of Paul.
2 Thessalonians 2:15
Therefore, brothers, stand firm and hold fast to the traditions that you were taught, either by an oral statement (our word) or
by a letter (written
tradition) of ours.
