Indeed, we are adults. That’s why it’s important to interpret the catechism in the eyes of faith, fidelity, and in the spirit of prayer. If we’re on call, we are working. Period. It is a requirement of our job, at that time/moment, for us to be 'available" to our employer and/or to our clients/customers/the general public (such as someone who works Emergency Services – a police officer, an EMT, etc.); therefore we are working and therefore we are not fully available to God.
Wow. Just wow.
There’s the spirit of Eucharist, the spirit of Community, the commitment to One Body-One Spirit, one Lord of All. Again, “might” is not even the question for many of us. More like “will” be distracted, major. Electronics are an excuse. What did the world do before the existence of these conveniences? They coped. They dealt with an hour of silence. They made the rest of the world wait for them. Again, otherwise you are not available to God. You are available and on High Alert for apparently whoever takes precedence over God.
In one of the extremely liberal parishes I attend (I attend a variety – from EF to NO), even they insist on all cell phones and pagers being completely off. Most of us have the good sense to leave our electornics in the car.
I’m definitely going to run this question by some good orthodox traditionalist priests as to whether having to be on call (apparently from Saturday afternoon through sunday evening?) is acceptable grounds to dispense with a Sunday obligation. The Catechism is there for interpretation by those trained to do so. It is not exhaustive for every possible situation, because that is not possible in the finite capacity of the document.
Sunday Mass is a big deal, no question. Not only do I not disagree with that – if I am sick or otherwise unable to attend on a weekend, it is distressing to me personally, as weekdays do not adequately replace. That said, if my job literally required me to be on High Alert non-stop from late Saturday afternnon through late Sunday evening, every single weekend, I would see how I could negotiate possibly some variance for that permanent availability, for religious reasons. People in other religions do so.
