Today is celebrated the Feast of St. John The Evangelist. And in respect thereof, today is the day to bring your bottle(s) of wine to the Church to have it blessed by a priest.
John was a fisherman before he and his brother James were called by Christ to become his apostles. John was the only apostle to stay with Jesus during the crucifixion. Afterwards, he joined with St. Peter to spread Christianity throughout Israel. John was later exiled to the island of Patmos where he received visions that he recounted in what is now the final chapter of the Bible, The Apocalypse.
John alone of the apostles did not die a martyr's death – though apparently there were several attempts made on his life. The most famous was an attempt to poison him that failed when John blessed his wine, drawing out the poison before John consumed the wine. It is in remembrance of that event that, on the Feast of St. John, people may bring wine to the Church that it be blessed and then consumed in his honor.
John 1: 1-5
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made through him; and without him was not anything made that hath been made. In him was life; and the life was the light of men. And the light shineth in the darkness; and the darkness apprehended it not.
Today's Feast was historically a special day of celebration for priests. Do have a happy Feast of St. John The Evangelist and may your wine be blessed.
