No need to read more into Scripture tan what He provides. IMHO, the Angel of the Lord probably was the same person as the Son, but if God had wanted to communicate that to us in Scripture, He would certainly have so presented it.
IMHO, those who study Scripture through faith in Christ, are given the proper understanding when they read the passage by the work of God the Holy Spirit in our human spirit, thereby further sanctifying our souls.
The is danger, however, in advancing the doctrines academically, independent of faith in Him.
If that were true, then the Holy Spirit would lead all christians to the same understanding. Can there be more than one interpretation of the Bible? No. The word "truth" is used several times in the New Testament. However, the plural version of the word "truth" never appears in Scripture. Therefore, there can only be one Truth. So how can there be over 20,000 non-Catholic Christian denominations all claiming to have the "Truth"
For that matter, aren't ALL non-Catholic Christians as individuals claiming "infallibility" when it comes to interpreting the Bible? Catholics only believe in the infallibility of the Papacy as an office. Which is more believable - one office holding infallibility or 400 million non-Catholic Christians who can't agree on the interpretation of Scripture all claiming "infallibility?" When it comes to interpreting Scripture, individual non-Catholic Christians claim the same infallibility as the Papacy. If one were to put two persons of the "same" non-Catholic Christian denomination (i.e., two Presybterians, two Lutherans, two Baptists, etc.) in separate rooms with a Bible and a notepad and ask them to write down their "interpretation" of the Bible, passage for passage, shouldn't they then produce the exact same interpretation? If guided by the Holy Spirit as Scripture states, the answer should be "Yes." But would that really happen? History has shown that the answer is "No." Now, in the case of Catholics, the Church which Christ founded and is with forever (Matthew 28:20) interprets the Bible, as guided by the Holy Spirit, (Mark 13:11) for the "sheep" (the faithful). The Church (not individuals) interpret Scripture. In Catholicism, Scripture is there for meditation, prayer and inspiration, not for individual interpretation to formulate doctrine or dogma.
