A Posada is the tradition of taking the figures of Mary and Joseph into homes for a night or two during Advent. As the figures are in a home there may be prayers and reflections as they enter and leave and the figures may be an occasion for devotions shared with friends, family and neighbours while they are in that home. They then move on to the next home that has volunteered to put them up for the night or
two, and so on through Advent.
A Posada blog is an idea to do something analogous with blogging. So instead of the actual clay or wood or whatever figures of Mary and Joseph we have a picture. Instead of homes we have blogs. Instead of family prayers we have a blog posting.
So the idea is that on Advent Sunday, I would post a picture of Mary and Joseph and offer some reflections and/or prayers for the occasion as my posting.
The next day someone else would post that same picture [either by posting it anew or by linking back to the 'original' image I posted] and offer their reflections and/or prayers, similarly.
They would also mention who is to post the following time and leave a comment on my blog at my Advent Posada posting to give the address of their posting [this would have to be the permalink, not just the blog address].
Then, hopefully, the next day someone else would
1) post the picture and make some prayerful reflection on their blog, and
2) make a mention of who is due to host the holy couple the following day
3) leave a comment at the previous day's posting with a link to their
new posting, and so on.
What should result is a chain of links as Mary and Joseph virtually
move from blog to blog day by day.
I will be participating in this. If you're interested as well, leave a comment at Nouslife: Posada blog chain for Advent.
