Answer:
Pope Leo XIII's 1893 letter Providentissimus Deus expresses concern about the growing trend among some Catholics to reject the authority of the Bible and to interpret its teachings in a way that is incompatible with the teachings of the Catholic Church. The letter argues that faith in the word of God as recorded in the Bible is essential to the Catholic faith, and that Catholics must accept the Bible as the inspired and infallible word of God.
Pope Leo XIII also expresses concern about the rise of modernist interpretations of the Bible, which he sees as a threat to the authority of the Church. He argues that the Bible must be interpreted in accordance with the teachings of the Church, and that any interpretation that contradicts those teachings is erroneous and must be rejected.
Furthermore, Pope Leo XIII argues that the Bible is a complex and multifaceted work, and that it must be studied and interpreted carefully in order to understand its true meaning. He encourages Catholics to engage in serious study of the Bible, and to seek guidance from the Church in their interpretation of its teachings.
