• Nonbelievers and enemies of Catholic Christianity often
accuse the Church of creating the belief in Mary's freedom
from original sin "the Immaculate Conception" in 1854 (as
the Church named the belief of Mary's freedom from the
wages of sin, death, "the Assumption" in 1950) when the
truths were defined.
Such an error is equivalent to saying that before Adam named
the animals and birds of creation in Gen 2:19-20 they did not
exist.
• Or that before the early Church in her Ecumenical Councils
named the belief of three persons in one God "the Trinity" and
the belief that there are two natures, human and divine in
the person of Jesus Christ "the Incarnation," the truths did
not exist.
In naming the content of Divine Revelation after God has
revealed it to us, the Church reflects a long Biblical tradition
and practice.
