Mark 14:22 - Jesus meant that the bread and fruit of the vine were memorials of His body and blood. This was a figure of speech. He did not mean that the bread and fruit of the vine literally became His body and blood.

I Corinthians 12:27 - a similar figure regarding Christ’s body

I Corinthians 11:23-26

Mark 14:25 - Jesus did drink of the fruit of the vine again on earth after His resurrection. “That day” shows that Jesus was pointing to a specific day when He would drink it again, which ties in with the examples we have of early Christians partaking of the Lord’s Supper on the first day of the week.

Mark 14:33. Jesus did not violate this verse by being anxious about His impending crucifixion because the verse is stressing the importance of bringing our troubles to God. This is exactly what Jesus did by praying in the garden.

Mark 14:36 - In a similar way, we must deny ourselves and obey God’s will in order to be pleasing to Him. Jesus may simply be praying that the whole ordeal would pass quickly, rather than praying that He would escape it completely. He knew it was His mission to die on the cross, so it would not make sense for Him to pray against His mission.
