“One can distinguish between two senses of Scripture: the literal and the spiritual….”
If you want to stick to the literal meaning, that’s your call. However, that’s not the official Catholic point of view.
You just quoted the CCC "“One can distinguish between two senses of Scripture: the literal and the spiritual….” And if you keep reading the CCC here, you will find that the spiritual sense which is divided into 3 senses is founded on the literal sense. That is, within the literal sense, there may be contained one or other or a combination of the spiritual senses. The literal sense is the foundation of biblical interpretation, it is that sense which the inspired author intends to convey through his words. Accordingly, your statement above makes no sense and contradicts the very quote you make from the CCC itself.
A “plain reading” of the Bible is almost inevitably an erroneous reading.
Hardly the case. A ‘plain reading’ is usually used in conjunction with the literal sense, i.e., the meaning of the sacred writer conveyed by the words themselves. For example, the first verse of the Bible “In the beginning God created the heavens and the earth.” However, by a ‘plain reading’ understood in this way, the literal sense does not necessarily follow. Sometimes the literal sense is the spiritual sense or a metaphorical sense. For example, the Bible speaks of the ‘arm of God.’ God has no body or arms so the literal sense here is not literally that God has an arm. It is a metaphor so what the sacred writer intends by ‘arm of God’ is something like ‘the strength of God’ which is the meaning the author intends to convey which is the literal sense of the passage.
The Bible contradicts itself all over the place–if you want to defend a literal reading of the Bible, be my guest. But first read the account of the Resurrection in all four Gospels. If each one is taken literally, and each one is the inspired word of God, you’ve got yourself some explaining to do.
God is the principle author of the Bible and every part of it. In this sense, it is inadmissible to hold that the Bible, the word of God, can contradict itself, i.e., God contradicting himself. It is also inadmissible to hold that the Bible contains any error as error is incompatible with God, the principle author of Scripture.
At the same time, God made use of the human authors of the Bible to transmit his word and as the CCC says ““In Sacred Scripture, God speaks to man in a human way.” And the word of God was transmitted to a people such as the Israelites in various times in a way that it could be at least potentially understood by them. So, their is a human element in Sacred Scripture, i.e, the human authors themselves and the times, conditions, and culture in which they wrote, and possibly a certain allowance of freedom so to speak even under divine inspiration that we need to take into account for the proper interpretation of Scripture and at the same time not excluding the principle author of Scripture, God.
