We catholics believe by faith in the the transformation of the bread into the body of Christ and the wine into the blood of Christ and it transformations staying. Maundy Thursday after evening mass the Eucharist is taken out of the altar shrine symbolizing that Jesus can not be found there because the passion starts and during that night it is put in a special altar built for the adoration of the people. This symbolizing us praying with him as the apostles did in the Garden of Getsemani.
Why seven? Seven in always a symbolic number in the Church and in The Bible, the visitation of seven churches could be related to the seven main churches in Rome.
It can be any seven. Some weeks we have done all in the Historic downtown, other times we have done 7 churches close to home, other times we have driven to Antigua. This year we only did 4 (3 downtown and 1 near home) the girls were too tires after a friends and family traditional lunch -Bacalao a la Viscaina, arroz, tamalitos, curtido, empanadas- we had that day.
