Saint Cecilia Catholic Community, where I am pastor, meets in a warehouse. The altar is at the front with the clergy seated behind it. We celebrate westbound. The congregation sits in a semi-circle in front of the altar.  The font is near the front door. The altar and font were built by the volunteer labor of one of our parishioners out of ordinary lumber. Yet all liturgical ministers, clerical and lay, are properly vested (no readers and Eucharistic ministers in street clothes!), and we sing 100% of our Sunday Mass every Sunday.
