I have deleted a submitted comment in which the writer assured me that, if X were to happen, "That is the day I walk out of the Church never to return".
I had better be frank about this.
Such a contingent threat of Apostasy, if seriously meant, suggests to me that the writer is in a most dangerous spiritual state.
It is true that PF treats the Church Militant (happily, there is no way he can get his hands on the Church Expectant and it is not within his mercifully limited power to "make a mess" in the Church Triumphant) as if it were some sort of private playground in which he can get up to whatever games he finds personally satisfying and heap up any number of his boasted "messes". But the Church is the Body of Christ. Not PF's playground; not mine; not yours.
There have been appallingly bad popes in the past and, depending on how long it is until the Eschaton, there very probably will be more of them in the future. None of that makes a nanogram of difference to the fact that the Catholic Church is the Ark of Salvation; the only and the essential Ark of Salvation.
And it is not a human and worldly 'membership organisation' which one can walk out of in a huff. You and I were incorporated into it by our Baptism. It is rooted in eternity; splendid as an army with banners; a terror to the fallen spirits; a wonder to the Angels.
If anything I have ever written has, however unintentionally, given any encouragement to the sort of unCatholic attitude which horrified me in that comment as I sat down to deal with it this morning, then, here and now, I repent of it.
If PF, or I, by our misconduct, drive one soul to "walk out of the Church", then he (or I) will have to answer for that in the day of Judgement. But the person who has "walked out never to return" will have the gravest charge of all to answer.
