Contradiction with Matthew 4:19
This verse speaks of following Jesus to become "fishers of men" rather than focusing on literal fishing successes, which contrasts with the miraculous catch of fish in John 21:6.
Matthew 4:19: And he saith unto them, Follow me, and I will make you fishers of men.
Contradiction with Luke 5:5
Here, the disciples initially fail to catch fish, similar to John 21:6, but it happens earlier in Jesus' ministry, creating a narrative tension regarding when and how success is achieved.
Luke 5:5: And Simon answering said unto him, Master, we have toiled all the night, and have taken nothing: nevertheless at thy word I will let down the net.
Contradiction with John 6:27
This verse emphasizes the importance of seeking spiritual food that endures to eternal life, contrasting with the physical abundance of fish in John 21:6.
John 6:27: Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed. [Labour not: or, Work not]
