Touchstone Magazine & the Society of Saint James offers an excellent Ecumenical calendar of the liturgical year. I buy a bunch each year and give them out as gifts.

O, Christmas Eve more beautiful than the days
How can Herod bear the light
That blinks in your darkness
And is celebrated and worshipped
His pride listens to no reason
How noisy it sounds to his ears
He tries to destroy the untaught ones
By killing untaught souls
And rises a crying in town and country
In Bethlehem and in the field
And awakes the spirit of Rachel
That starts haunting field and meadow
- Excerpt from the 17th century dramatic play “The Gijsbrecht van
Aemstel” by the Dutch playwriter Joost van den Vondel
