Was Jesus a pope

No Jesus was dead long before the formation of the Roman church. He only asked his disiples to spread his Words and example. No. Matthew 16:18 was a later insertion to justify the appointment of a Pope. Peter is traditionally regarded as the first Pope by the Catholics.

16:18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
