peter,but he repented afterwards..
In the Gospels, Jesus tells Peter the night before the Crucifixion that Peter would deny knowing him three times, before the cock crowed the next morning. On the third denial, "the cock crew", and Peter realizes Jesus had been right.
Never knew he ever excisted, no proof of that
Saint Peter the Apostle was probably in his mid 30s at the time of the crucifixion of Jesus.
Peter
Peter denied Jesus three times. Jesus foretold that Peter would deny him three times in Mark 14:30, and he did.
Simon Peter, called at the same time was his brother Andrew.
When Peter denied Jesus for the second time, he was standing in the courtyard of the high priest, warming himself by the fire alongside others. A servant girl approached him and recognized him as one of Jesus' followers, prompting Peter to deny knowing Jesus again. This moment highlighted his fear and confusion during the tumultuous events surrounding Jesus' arrest.
Peter denyed knowing Jesus.
peter betrayed jesus
There is no record of that having occurred.
Judas was the disciple who betrayed Jesus' just BEFORE his death...Peter 'disowned' Jesus during his trial, but later apologized and was forgiven(Matthew 26:69-75)...but as far as any one 'disciple' who disowned Jesus AFTER his death, the only mention is of Hymenaeus, Alexander and Philetus (1 Timothy 1:19+20/2Timothy 2:16-19) who became apostate and were put out of the congregation.There have been many proclaimed 'disciples' of Christ who have 'disowned Jesus' by their works, in the centuries since his death, as was prophesied at Matthew 13:24, 25, 37-39(2 Thessalonians 2:3+4, 6-12).At Acts 20:29+30, Paul warns us clearly..."I know that after I leave, savage wolves will come in among you and will not spare the flock.Even from your own number men will arise and distort the truth in order to draw away disciples after them."(NIV) This happened after Jesus' death, increasing after the death of the apostles, and continues to happen today (Titus 1:16). Peter also warned thatthere would be "...false teachers among you, who will secretly bring in destructive opinions. They will even deny the Master who bought them...many will follow their licentious ways, and because of these teachers the way of truth will be maligned".(2 Peter 2:1+2 NRSV).Jesus said that 'by their fruitage you will recognize these men'(Matthew 7:15-20)
