St. Ignatius of Antioch

Wiki:  (also known as Theophorus from Greek Θεοφόρος "God-bearer") (ca. 35 or 50-between 98 and 117)^[1] was among the Apostolic Fathers, was the third Bishop and Patriarch of Antioch, and was a student of John the Apostle. En route to his martyrdom in Rome, Ignatius wrote a series of letters which have been preserved as an example of very early Christian theology. Important topics addressed in these letters include ecclesiology, the sacraments, and the role of bishops.
Epistles attributed to St. Ignatius report his arrest by the authorities and travel to Rome:

“

From Syria even to Rome I fight with wild beasts, by land and sea, by night and by day, being bound amidst ten leopards, even a company of soldiers, who only grow worse when they are kindly treated. —Ignatius to the Romans, 5.

”

Along the route he wrote six letters to the churches in the region and one to a fellow bishop.
He was sentenced to die in the Colosseum, to be eaten by lions.^[5]
In his Chronicle, Eusebius gives the date of his death as AA 2124 (2124 years after Adam), which would amount to the 11th year of Trajan, i.e. 108 AD.^[6] His body lies entombed under St. Peter's Basilica in Rome.

 
The seven letters considered to be authentic are:
To the Ephesians
To the Magnesians
To the Philadelphians
To the Romans
To the Smyrnaeans
To the Trallians
To Polycarp
