Submit to the Advent Reflection Book

We will again publish a parishioner advent reflection book this year! Simply read the readings for one or more days during Advent and submit a short (no more than 250 word) reflection on one or all of the readings. The reflections should simply answer the question “what do these readings say to me and my life?” Reflections are due November 1. Each reflection will be reviewed and then we will choose one for each day to be published in the book and distributed to our parishioners during Advent 2017! You can find a list of readings for each day of Advent on the parish website at smip.org/adultformation. Please submit your reflections to eburt@smip.org. All ages are welcome to submit!
