I just came across these quotes and thought they would be applicable to post in this discussion.
From the Catholic Encyclopedia article on Heresy:
"Towards material heretics her (the Church's) conduct is ruled by the saying of St. Augustine: "Those are by no means to be accounted heretics who do not defend their false and perverse opinions with pertinacious zeal (animositas), especially when their error is not the fruit of audacious presumption but has been communicated to them by seduced and lapsed parents, and when they are seeking the truth with cautious solicitude and ready to be corrected" (P. L., XXXIII, ep. xliii, 160). Pius IX, in a letter to the bishops of Italy (10 Aug., 1863), restates this Catholic doctrine (on invincible ignorance)...."
This is a perfect example that would exonerate the nine-year-old boy we were speaking about.
And from the Catholic Encyclopedia article on Orthodoxy:
"The Church, likewise, in its zeal for purity of faith and teaching, has rigorously adhered to the example set by the Apostles and Early Fathers. This is manifest in its whole history, but especially in such champions of the faith as Athansius, in councils, condemnations of heresy, and its definitions of revealed truth. That orthodox faith is requisite for salvation is a defined doctrine of the Church. "Whosoever wishes to be saved", declares the Athanasian Creed, "must first of all hold integral and inviolate the Catholic faith, without which he shall surely be eternally lost". Numerous councils and papal decisions have reiterated this dogma (cf. Council of Florence, Denz., 714; Prof. of Faith of Pius IV, Denz., 1000; condemnation of Indifferentism and Latitudinarianism in the Syll. of Pius IX, Denz., 1715, 1718; Council of the Vatican, "De Fide". can. vi, Denz., 1815, condemnation of the Modernistic position regarding the nature and origin of dogma, Encyc. "Pascendi Dominici Gregis", 1907, Denz., 2079). While truth must be intolerant of error (II Cor., vi, 14, 15), the Church does not deny the possibility of salvation of those earnest and sincere persons outside her fold who live and die in invincible ignorance of the true faith (cf. Council of the Vatican, Sess. III, cp. iii, Denz.,1794; S Aug., Ep.xliii ad Galerium). (See CHURCH; FAITH; PROTESTANT CONFESSIONS OF FAITH; HERESY; INDIFFERENTISM.) "
This confirms the same interpretation that I've been saying for the Pope Pius IX quote.
