Please could you explain the difference using a Catholic that falls into both and a Protestant that falls into both to help me see clearer?

A summary of each would be great.

Thanks.
 
Hello there,

My understanding of the two is as follows:

Material Heresy is simply when one who holds the Christian faith but denies any article of the faith that has been defined and taught by the Catholic Church (dogma). For example, if you were to deny the Immaculate Conception, you would be in, at least, Material Heresy.

Formal Heresy is when you willfully, and with knowledge and understanding, reject an article of the faith as taught and defined by the Catholic Church. Formal Heresy is far more severe because it is done with knowledge and understanding that the particular thing denied is taught by the Church and yet the position is held with obstinance.

Basically, when Material Heresy is committed alone, it is usually a mistake done in innocence or ignorance, but Formal Heresy is malicious because it is done willfully and with intent.

Examples:

If a poorly catechized Catholic denies the existence of Purgatory, but does it through ignorance or misapprehension and with no intent to disobey the Church, he would be in Material Heresy, but not Formal Heresy (because he did not know that such a thing was heretical nor did he have intent to disobey the Church). Of course, he might be guilty of not bothering to learn his faith, but he would not be guilty of Formal Heresy. If he had known what the Church teaches about Purgatory, and yet insists that there is no Purgatory, then he is in Formal Heresy.

A Catholic who knows and understands what the Church teaches about salvation and yet decides that salvation is by ‘faith alone’ and then subsequently leaves the Catholic Church, has committed Formal Heresy.

If you had a Southern Baptist who was born and raised in his Protestant church with no knowledge that his church’s teachings were heretical, then he would be a material heretic, but not a formal heretic. If he, on the other hand, knew and understood that the Catholic Church teaches otherwise then he would be a formal heretic.

If you had a Protestant that is a militant anti-Catholic that knows and understands what the Church teaches about Mary, for example, and yet willfully rejects those teachings, he is a Formal Heretic.

It should also be noted that heresy differs from apostasy in that heresy is a denial of some points of the faith, but not all. Apostasy is a denial of the Christian faith entirely. One who left the Catholic Church and became a Muslim would not be a heretic, he would be an apostate.

Also it should be noted that those that are separated from the Roman Pontiff, but yet, do not deny any article of the faith are schismatics (and are neither, necessarily, heretics or apostates).

Heresy and apostasy are both sins against Faith and very grave. Schism is a sin against Charity and is also grave, but not as bad as the former two.

Pax Domini sit semper tecum!
 
“The Church expressly distinguishes between ‘formal’ and ‘material’ heretics. A ‘formal’ heretic rejects the Church and its teaching absolutely and with full deliberation; a ‘material’ heretic rejects the Church from lack of knowledge, being influenced by false prejudice or by an anti-Catholic upbringing. St. Augustine forbids us to blame a man for being a heretic because he was born of heretical parents, provided that he does not with obstinate self-assurance shut out all better knowledge, but seeks the truth simply and loyally. Whenever the Church has such honest enquirers before her, she remembers that our Lord condemned Pharisaism but not the individual Pharisee, that He held deep and loving intercourse with Nicodemus, and allowed Himself to be invited by Simon. The spirit of the Church in her dealings with souls may be stated in St. Augustine’s words: ‘Love men, slay error!’”

I thought PulvisEtCnis’ explanation was superb. Did that clarify for you enough?
Thank you 🙂

Modern Catholic Dictionary:

HERESY. Commonly refers to a doctrinal belief held in opposition to the recognized standards of an established system of thought. Theologically it means an opinion at variance with the authorized teachings of any church, notably the Christian, and especially when this promotes separation from the main body of faithful believers.

In the Roman Catholic Church, heresy has a very specific meaning. Anyone who, after receiving baptism, while remaining nominally a Christian, pertinaciously denies or doubts any of the truths that must be believed with divine and Catholic faith is considered a heretic. Accordingly four elements must be verified to constitute formal heresy; previous valid baptism, which need not have been in the Catholic Church; external profession of still being a Christian, otherwise a person becomes an apostate; outright denial or positive doubt regarding a truth that the Catholic Church has actually proposed as revealed by God; and the disbelief must be morally culpable, where a nominal Christian refuses to accept what he knows is a doctrinal imperative.

Objectively, therefore, to become a heretic in the strict canonical sense and be excommunicated from the faithful, one must deny or question a truth that is taught not merely on the authority of the Church but on the word of God revealed in the Scriptures or sacred tradition. Subjectively a person must recognize his obligation to believe. If he acts in good faith, as with most persons brought up in non-Catholic surroundings, the heresy is only material and implies neither guilt nor sin against faith. (Etym. Latin haeresis, from the Greek hairesis, a taking, choice, sect, heresy.)
