Let the Son shine into your heart
Solstice is the darkest part of the year in the northern hemisphere. The days become troublingly short, with night falling before afternoon is over. For those with “seasonal affective disorder” it can be a time of dangerous heavy depression.
The Church chose the period near Solstice to replace the pagan bacchanal celebrations with holy gatherings to honor the Nativity of Jesus Christ
In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.
– John 1:1-5
