John Calvin Commentary John 21:1

"After these things Jesus manifested himself again to the disciples at the sea of Tiberias; and he manifested [himself] on this wise." — John 21:1 (ASV)

After these things Jesus manifested himself again. The Evangelist still labors to prove the resurrection of Christ and relates that He appeared to seven disciples, among whom he mentions Thomas—not so much out of respect for him, as because his testimony ought to be more readily believed in proportion to the obstinacy of his unbelief.

The Evangelist enters into sufficient detail, for he carefully collects all the circumstances that contribute to proving the truth of the history. We have previously mentioned that the Lake of Tiberias, according to the Hebrew custom, is called the Sea of Tiberias.
