Hi David
I thought that the position of the Church was that apart from divine personal revelation we could not know, but that some receive such revelation. In support of this I would offer the Church approved revelations of Lucy from Fatima to whom was revealed that she (and the other children) would go to Heaven. Am I mistaken?
I believe the quote from David was misunderstood by him. Let’s look at it more closely.
David Filmer:
But the Church teaches that we cannot be
absolutely certain if we are in a State of Grace:
For as no pious person ought to doubt the mercy of God, the merit of Christ and the virtue and efficacy of the sacraments, so each one, when he considers himself and his own weakness and indisposition, may have fear and apprehension concerning his own grace, since no one can know with the certainty of faith, which cannot be subject to error, that he has obtained the grace of God. [Council of Trent, Sixth Session]
While David did not cite the specific Canon number in this quote, which I was unable to find, I did note these two Canons that speak about not knowing with certainty whether one will persevere in grace to the end, without special revelation, which is what was given to Lucia, as Philthy mentioned. The Church teaches us to HOPE that God, in His mercy will grant us an eternal recompense if one keeps the commandments and perseveres to the end. The Canons on Justification say nothing about "knowing that a person has obtained the grace of God – at least, none that I could see
here.
Many of us will remember the Baltimore Catechism
Act of Hope, which is a theological virtue, and very necessary for one’s spiritual life. Saying that one should fear concerning his own grace, is destructive of hope, and is not at all what the Church teaches us. It may be that David was speaking about the grace of final perseverance.
CANON XVI.-If any one saith, that he will for certain, of an absolute and infallible certainty, have that great gift of
perseverance unto the end,-unless he have learned this by special revelation; let him be anathema.
CANON XXVI.-If any one saith, that the just ought not, for their good works done in God, to expect and hope for an eternal recompense from God, through His mercy and the merit of Jesus Christ,** if so be that they persevere to the end** in well doing and in keeping the divine commandments; let him be anathema.
Finally, Session VI teaches further, that our help in believing, hoping, loving is dependent upon the help of the Holy Spirit in order to obtain justification.
CANON III.-If any one saith, that
without the prevenient inspiration of the Holy Ghost, and
without his help, man can believe, hope, love, or be penitent as he ought, so as that the grace of Justification may be bestowed upon him; let him be anathema.
