Here are links to my four posts on the movements of Advent in Year A of the lectionary, as I see them
Advent 101: Waiting
Advent 102: Preparing
Advent 103: Rejoicing with a followup here
Advent 104: Solidarity
The four Sundays were treated with their music on these pages:
Second Sunday and 2016 "Second Thoughts" here
Third Sunday (none)
Fourth Sunday with more on St. Joseph as a just man and father here.
And here are links to some of my Advent songs in the "Songstories" series.
Thy Kingdom Come
Walk in the Reign
Sing We Maranatha
The Wilderness Awaits You
That's for quick reference and archiving purposes. Thank you for reading.
