Not that it’s actually part of the sacrament or anything, but it has been the custom in some sections of Scottish presbyterianism to hold several days’ worth of preparatory services ahead of dispensing the sacrament of the Lord’s Supper in any particular congregation.
The services are intended to be helpful to people as they prepare for taking part in the sacrament, and generally they follow a series of fairly well defined themes for each day. On Thursday it is customary that people devote themselves to confession and prayer. On Friday the day is meant to be spent in self-examination. Saturday is for more direct preparation for the ordinance itself, concentrating on the meaning of the sacrament and the person and work of Christ it commemorates. On the Lord’s day the sacrament is administered in the morning service, and then there is a thanksgiving service on Monday.
The church services are of course only meant to help people in their personal preparation, and of course it is not necessary to attend them in order to take part in the sacrament, and of course because of the logistics they really work best in the context of relatively infrequent celebrations of the sacrament. Still the five-day setup (‘the communion season’) can be seen as a useful and beneficial arrangement, allowing the whole congregation to prepare together under the preaching of the Word and giving a structured way of carrying out a duty, ie of preparation, which might otherwise be easily neglected or only done hastily or patchily.
Anyway, that’s just a heads-up to let you know I’ll be otherwise occupied for the next few days and unlikely to be around here much.
