Don’t worry about my homework, Jr.
Here’s more crap from the GIRM:
303. In building new churches, it is preferable for a single altar to be erected, one that in the gathering of the faithful will signify the one Christ and the one Eucharist of the Church.
In already existing churches, however, when the old altar is so positioned that it makes the people’s participation difficult but cannot be moved without damage to artistic value, another fixed altar, skillfully made and properly dedicated, should be erected and the sacred rites celebrated on it alone. In order that the attention of the faithful not be distracted from the new altar, the old altar should not be decorated in any special way.
“Don’t worry about my homework, Jr.”
Well, someone has to since you and your parents didn’t worry about you doing yours. And, again, the GIRM is not the missal and the missal is not the GIRM. You honestly have never read these documents before have you?
