St. Peter Speaking on Behalf of All the Apostles

Consider: (1) Jesus saith to them: But whom do you say that I am? *Simon Peter answered and said: Thou art Christ, the Son of the living God.* (Matt. 16:15-16.) (Italics added.) (2) Then Jesus said to the twelve: Will you also go away? And Simon Peter answered him: *Lord, to whom shall we go? Thou hast the words of eternal life.* (John 6:68-69.) (Italics added.) (3) Then Peter answering, said to Him: *Behold we have left all things, and have followed Thee: what therefore shall we have?* (Matt. 19:27.) (Italics added.) (4) And Peter said to Him: *Lord, dost thou speak this parable to us, or likewise to all?* (Luke 12:41) (Italics added.) (5) Now when they had heard these things, they had compunction in their heart, and said to Peter, and to the rest of the apostles: What shall we do, men and brethren? But Peter said to them: *Do penance, and be baptized every one of you in the name of Jesus Christ, for the remission of your sins: and you shall receive the gift of the Holy Ghost.* (Acts 2:37-38.) (Italics added.) QUESTION: Does anyone know of a complete list of occasions in the New Testament where St. Peter speaks on behalf of *all* the Apostles?
