In Kol Nidrei, one says
All vows, and prohibitions, and oaths, and consecrations, and konams and konasi and any synonymous terms, that we may vow, or swear, or consecrate, or prohibit upon ourselves, from the previous Day of Atonement until this Day of Atonement and ... from this Day of Atonement until the Day of Atonement that will come for our benefit. Regarding all of them, we repudiate them. All of them are undone, abandoned, cancelled, null and void, not in force, and not in effect. Our vows are no longer vows, and our prohibitions are no longer prohibitions, and our oaths are no longer oaths."
Does this mean that I am allowed to make a false (future, and not-interpersonal) oath nowadays?
The Wikipedia article says that many were opposed to this prayer for this reason. Yet, now that we do say it, why does one have to keep any not-interpersonal vow nowadays?
