Sacred Scripture has two levels of meaning:
- The words refer to things. This includes literal and figurative assertions.
Example of a literal assertion:
[Matthew]
{2:1} And so, when Jesus had been born in Bethlehem of Judah, in the days of king Herod, behold, Magi from the east arrived in Jerusalem,
Jesus was literally born in Bethlehem in Judah, during the reign of king Herod, and Magi literally arrived from the East in Jerusalem.
[Hebrews]
{12:29} For our God is a consuming fire.
God is not literally a fire, consuming or otherwise. This is a figure of speech, indicating that God is active, that he judges and punishes, that he actively accomplishes his will and nothing can stand in his way.
- The things refer to other things. This is called the spiritual sense, and requires interpretation.
Example: in the Song of Songs, the words refer to the marriage of Solomon to a woman from Africa. The groom represents Christ and the bride represents the Church on the spiritual level of meaning.
“Hence it is plain that nothing false can ever underlie the literal sense of Holy Writ.”
St. Thomas Aquinas, Summa Theologica, I, Q 1, A 1.
By literal sense, St. Thomas means the literal/figurative level of meaning. Since the spiritual level of meaning is based upon the literal/figurative level of meaning, it is not possible for the literal/figurative level of meaning to be false while the spiritual level of meaning is true.
“…they put forward again the opinion, already often condemned, which asserts that immunity from error extends only to those parts of the Bible that treat of God or of moral and religious matters.” (Pope Pius XII, Humani Generis, n. 22).
The idea that there are errors in the Bible on history, geography, science, biology, or any other subject area is a condemned opinion and is material heresy.
Now certainly one may consider which assertions of the Bible are literal and which are figurative, and one may consider which truths are being asserted by the literal/figurative and by the spiritual levels of meaning. But if any one claims that the Bible asserts an error or a falsehood on any subject, that person is claiming a condemned idea.
Concerning the question as to what constitutes error, how is it that you yourselves use the word error to state that there are errors in the Bible, but then you claim not to know what the word means? An error is a false assertion. At times it may be difficult to understand what the Bible is asserting, but never does the Bible assert any falsehood.
“But
it is absolutely wrong and forbidden, either to narrow inspiration to certain parts only of Holy Scripture, or to admit that the sacred writer has erred… For all the books which the Church receives as sacred and canonical, are written wholly and entirely, with all their parts, at the dictation of the Holy Spirit; and so far is it from being possible that any error can co-exist with inspiration, that inspiration not only is essentially incompatible with error, but excludes and rejects it as absolutely and necessarily as it is impossible that God Himself, the supreme Truth, can utter that which is not true. This is the ancient and unchanging faith of the Church,
solemnly defined in the Councils of Florence and of Trent, and finally confirmed and more expressly formulated by the Council of the Vatican.” (Pope Leo XIII, Providentissimus Deus, n. 20).
