Russell Brand announces baptism after months-long spiritual journey: 'Taking the plunge' (www.christianpost.com)

One cannot expect mockumentaries teach real theology or history.

The Bible doesn’t indicate where Andrew dies either. Or Bartholomew. Or Thomas. Or…, or, or… We get to know much more about their routes, their missionary acts, and about their passions from other sources.
These trendy documentaries are mostly based on pop- historians’ fabulations and interpretation of some events – many a times with the clear purpose to defamate – and I think they are to be trusted just as much as Bram Stoker about Vlad the Impaler. So be very careful about what you watch on youtube.
There are even some that claim Peter didn’t even die by crucifiction, but the Early Church fathers are unanimous in claiming that Peter died in Rome, by crucifixion, during the persecution of Nero. Eusebius (AD 325) claimed in his Ecclesiastical History that all the apostles were martyred except for John. When he reported the crucifixion of Peter and the beheading of Paul he was simply passing along a tradition which has been the unanimous opinion of the church for two hundred years.

The best reference about Peter’s crucifiction is found in the Bible ( not about the location, indeed):

1. -> John chapter 21, in which the Lord told Peter, “I assure you: When you were young, you would tie your belt and walk wherever you wanted. But when you grow older, you will stretch out your hands and someone else will tie you and carry you where you don’t want to go.” John reported, (probably after Peter died) “He said this to signify by what kind of death he would glorify God.”

2. -> another reference to the martyrdom of Peter comes from the letter of Clement of Rome (about AD 90). He said, in his Letter to the Corinthians, “Let us take the noble examples of our own generation. Through jealousy and envy the greatest and most just pillars of the Church were persecuted, and came even unto death… Peter, through unjust envy, endured not one or two but many labours, and at last, having delivered his testimony, departed unto the place of glory due to him.”
…therefore we have execution (2) by crucifiction (1).

About the location:

-> Ignatius, in his Letter to the Romans about AD 110 claimed that Peter was bishop of Rome.

-> Irenaeus of Lyon, about AD 180, agrees that Peter served in Rome.

-> Tertullian, about AD 195 declared “But if you are near Italy, you have Rome, where authority is at hand for us too. What a happy church that is, on which the apostles poured out their whole doctrine with their blood; where Peter had a passion like that of the Lord, where Paul was crowned with the death of John (the Baptist, ie. by being beheaded).

-> Dionysius of Corinth, also about AD 200 “You (Pope Soter) have also, by your very admonition, brought together the planting that was made by Peter and Paul at Rome and at Corinth; for both of them alike planted in our Corinth and taught us; and both alike, teaching similarly in Italy, suffered martyrdom at the same time”

Now about the hot potato: a quick search on the internet about greek grammar and some of it’s rules will provide you hundreds of explanations from (pay attention!) greek speakers (yes, there are forums, there are topics and there is greek grammar; I talk about natives, the greek speakers… that explain nice and simple, sometimes sophisticated, in english, from the regular shop-worker, electrician and going up right to the academicians) why Yeshua is IESOUS ( in english Jesus). But you could have figured that out from the more visible Moshe/Moishe – Moses as well. (The miracle of transliteration!)
