A pope who basically just stuck around long enough to see the 5th Century start, Anastasius was elected pope in November 399, soon after the death of Siricius. During his short reign, Anastasius I condemned the heresy of Origenism, a sect that believed primarily in universal salvation (i.e. nobody goes to Hell) and the soul existing before conception (it doesn’t). He also encouraged North African Catholics to battle Donatism, the “holier than thou” heresy that says only properly pious ministers can confer valid sacraments. Anastasius I died in December of 401. His feast was originally celebrated April 27, but was eventually changed to December 19.

Anastasius had quite the arsenal of saintly friends, having been good buddies with the likes of St. Augustine and St. Jerome. In fact, St. Jerome once wrote about our good pope, saying Anastasius I was a “man of great holiness who was rich in poverty.”

Fun fact: We have still in existence a letter written by St. Anastasius I to Simplicianus, then the bishop of Milan. The letter was written to actively discourage the Church there from reading the heretical books of Origen, and can be read in full here. (Don’t worry, it’s short.)

Around the year 400, the Chrysanthemum (flower) is first introduced into Japan after being grown in China for many centuries before.
