ICD-10 code D70 for Neutropenia is a medical classification as listed by WHO under the range -Other disorders of blood and blood-forming organs .
Jesus included Peter in his inner circle when he took Peter, James, and John into the house of Jairus, where Jesus raised Jairus' daughter from the dead (Mark 5:35-43). Later, Peter was among those same disciples Jesus chose to witness the transfiguration (Matthew 17:1-9).
The Jerusalem burial of Peter is not currently taught by the Church of Rome. Thus, it appears to me, at least, that scholars (including Catholic ones) tend to understand that it is questionable if Peter was buried in Rome and if his body is actually in St. Peterâs Basilica in Vatican City.
