Jesus is just what the doctor ordered — every doctor, in fact, when the doctors in question are the Doctors of the Church.
And the most recently named of those — though the earliest in history — is St. Irenaeus of Lyon.
St. Irenaeus was born in Asia Minor (modern-day Turkey) around the year 130, and as a youth converted to Christianity under the guidance of Bishop Polycarp. St. Bishop Polycarp in turn had been a disciple of the apostle St. John.
