Letter 24

Isidore of PelusiumUnknown|isidore pelusium
From: Isidore of Pelusium, monk
To: An inquirer
Date: ~410 AD
Context: Isidore explains Christ's words about becoming like children (Matthew 18:3).

When Christ said, "Unless you turn and become like children, you will never enter the kingdom of heaven," he was not commanding a regression to childhood. He was not asking us to become naive or foolish. What children possess, which adults have lost, is simplicity — freedom from malice, envy, and the obsessive calculation of advantage. A child does not nurse grudges or scheme for status. That is the quality Christ demands: not ignorance, but innocence of heart. Be as sharp as you like in understanding — just be simple in your dealings with others.
