Maundy Thursday begins the Three Days (or Triduum), remembering the new commandment that Christ gave us in word and deed as he taught us how to love one another, washing our feet as a servant. We also celebrate the Lord’s Supper, remembering the meal Christ shared with his disciples before his death.
Historically, this was the traditional day in which those who had undergone a period of public penance under church discipline would be restored to full communion.
