Im not sure what are 'flawed interpretations of “Mystici Corporis”. Having grown up with Pius XII, at the time, we all thought his letter was magnificient.
I would quite agree–it is magnificent. The “flawed interpretation” involves adding a layer to what is required for Church membership rather than viewing his writing in the context of the clear teaching on Baptism.
It adds a lot of weight to a definition of the Mystical Body of Christ:
But, according to Vatican One, Mystici Corporis cannot break continuity with what the Church always has taught–in this case, the Church teaches that Baptism
alone makes one a member of this Mystical Body of Christ. Pius’ document must be read through that lens.
quote: Mystici Corporis:
22. Actually only those are to be included as members of the Church who have been baptized and profess the true faith,
Since there are
several obvious exceptions to this as a rule (baptized infants, martyred catechumens, etc.), Pius would appear to be stating that the “norm” for membership is baptism coupled with profession of true faith by those
capable of professing it. In this way, this phrase can be understood in harmony with the Church’s strict and clear teaching that baptism by
itself makes one a “default” member of the Church.
and who have not been so unfortunate as to separate themselves from the unity of the Body, or been excluded by legitimate authority for grave faults committed.
Here he refers to those who have separated
themselves from the unity of the Body–consciously–as well as those who have been penalized by the Church (excommunicated, interdicted, etc.)
“For in one spirit” says the Apostle, “were we all baptized into one Body, whether Jews or Gentiles, whether bond or free.”[17] As therefore in the true Christian community there is only one Body, one Spirit, one Lord, and one Baptism, so there can be only one faith.[18]
One Baptism–which is why
all baptisms properly performed–even if administerd by an
atheist who intends to do what the Church intends in Baptism–are valid.
And therefore, if a man refuse to hear the Church, let him be considered - so the Lord commands - as a heathen and a publican. [19]
Those baptized who willfully and consciously
reject the Church are in this category, but
not those who don’t willfully and consciously reject the Church…
It follows that those who are divided in faith or government cannot be living in the unity of such a Body, nor can they be living the life of its one Divine Spirit.
True–those who have made a
choice against faith and Church are, practically speaking, “severed” members, no longer united with the Body or the Spirit.
The reall interpretation problem is with “profess the true faith”–it can’t properly be interpreted to mean that you must be “visibly Catholic” to be a member of the Church, because the Church’s constant teaching on Baptism contradicts this concept.
