A common misinterpretation treats this verse as endorsing secret or esoteric teachings known only to Paul and not recorded in Scripture, undermining the sufficiency of the Bible; instead, it reinforces that Paul's oral instructions aligned with his epistles, as he urges remembrance to correct misunderstandings without implying hidden doctrines.
II Thessalonians 2:5
King James Version (1769)
5 Remember ye not, that, when I was yet with you, I told you these things?
Paul reminds the Thessalonian believers of his prior personal instruction on end-times events, such as the apostasy and the revelation of the man of sin before the Day of the Lord, underscoring the continuity between his oral teaching and the written letter to affirm doctrinal truth and prevent deception about Christ's return.
