I would be extremely annoyed if the only way to get the computer's attention were to enter the Lord's Prayer (or any other text of similar length) :-). I might well express my annoyance using the word "ritual". But it would still feel much much less ritual-y than if I were using the Lord's Prayer in a more conventional manner, because there would still be no element of psychological/spiritual/social significance to the person performing the action.

(And, although it would still be the case that you have to enter all those words in order to get the computer's attention, and therefore they have instrumental purpose, it seems to me like that's a harder argument to make with a straight face when the arbitrary complexity of the actions you're taking becomes very large.)

I agree (of course) that it's complicated, and not an all-or-nothing affair. As I said, I consider C-A-D only about 99.5% not a ritual. The Lord's Prayer version might be only 90% not a ritual.

Curiously, in one respect using the Lord's Prayer to try to get God's attention is less ritual-y than using it to try to get a computer's: everything in that prayer is there for an actual instrumental purpose! Someone praying it sincerely isn't just saying "forgive us our sins" because those are the traditionally mandated words[1], but also because they would like their sins forgiven and they at-least-kinda-think that saying those words will make that happen a bit more reliably.

[1] Well, depending on what sort of traditional you want to be you might have to say "trespasses" instead.
