To elaborate on the Magisterium of the Catholic Church is our mission on Plinthos (Gk. "brick"); and to do so anonymously, so that, like any brick in the wall, we might do our little part in the strength of the structure of humanity almost unnoticed.
Blessed be the God and Father of our Lord Jesus Christ, who hath blessed [Mary] with spiritual blessings in heavenly places, in Christ: As he chose [her] in him before the foundation of the world, that [she] should be holy and unspotted in his sight in charity. Who hath predestinated [her] unto the adoption of [daughter] through Jesus Christ unto himself: according to the purpose of his will: Unto the praise of the glory of his grace, in which he hath graced [her] in his beloved son. In whom [she] also [is] called by lot, being predestinated according to the purpose of him who worketh all things according to the counsel of his will. That [she] may be unto the praise of his glory...
Thus the second reading (ordinary form), of the Mass of the Immaculate Conception, which applies a fortiori to Mary, created by God without the stain of original sin, today.
Happy Feast of the Immaculate Conception!
Below, enjoy some Gregorian chant for the feast, and sing along!
