Contradiction with Matthew 5:17
This verse emphasizes the fulfillment of the law, while Revelation 1:10 describes a prophetic vision, which might be seen as introducing new revelation rather than fulfilling the old.
Matthew 5:17: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Contradiction with John 1:18
This verse states no one has seen God, implying a contradiction where John in Revelation has a direct spiritual encounter.
John 1:18: No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared [him].
Contradiction with 1 Thessalonians 5:2
This verse describes the day of the Lord as coming unexpectedly, which could contrast with John's prepared reception on the Lord's Day.
1 Thessalonians 5:2: For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
Contradiction with Matthew 24:36
This verse states that no one knows the timing of the Lord's day, contrasting with John's specific identification of it in Revelation 1:10.
Matthew 24:36: But of that day and hour knoweth no [man], no, not the angels of heaven, but my Father only.
Contradiction with Colossians 2:16-17
These verses caution against judging in matters of religious observance, suggesting a contrast with emphasizing a specific "Lord's Day" as Revelation 1:10 does.
Colossians 2:16-17: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: [in meat...: or, for eating and drinking] [respect: or, part]
Contradiction with Acts 1:7
This verse indicates that times and seasons are under God's authority alone, potentially conflicting with John's awareness of the Lord's Day.
Acts 1:7: And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
Contradiction with Matthew 6:34
The emphasis on not worrying about tomorrow could contradict the idea of anticipating or being in the spirit on a specific future "Lord's Day."
Matthew 6:34: Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day [is] the evil thereof.
