First, regarding this question, I would like to quote something from the link given in the original post.
This search of the Word is important, not because it affects salvation, but because it answers the questions posed on whether Jesus kept His Word,
and whether the Bible is true in this matter.
So, contrary to what some may strive to believe, no one here seems to be claiming that thinking Christ died on a Friday will cost you your
salvation.
However, as the OP said:
So many TV moneygrabers who call themselves ministers seem to contort themselves into half days, etc, etc in counting from good friday to
sunday morning........its laughable....
In an effort to not contort myself too miserably, the "half days" as you put it does work, and I'll explain how.
First, as of now it is about 1 in the afternoon here. Were someone to ask me what I had for dinner today, I would look at then a little strange, look
to a clock, and then continue to stare at them until they explained themselves. In the west, we start our days when we rise. Therefore, even if it was
a mere 8 hours ago, I still had dinner yesterday, not today.
If you were to ask me what I had for dinner three days ago, I would think back to Saturday to recall what I had eaten. Were we focused on a day being
a 24-hour period, I would relate what I had for dinner on Friday. After all, 72 hours ago, it was 1 PM on Saturday. Therefore, by a 24-hour
understanding, my dinner that took place 3 days ago would have to be on Friday night, as, exactly 3 days ago, I had not yet had dinner on Saturday.
Ok, a little contorting because, without a diagram, it is difficult for me to describe.
The Jews, unlike us, consider a day to begin at sunset. The first paragraph of the original links explains that in saying the passover lamb was
prepared between 3 and 6 PM because a Sabbath began that night. So, in some sense, just as we refer to yesterday as being everything that took place
before we went to bed, so the Israelites could refer to yesterday as being that which took place before the last sunset.
It sounds strange to us because it uses the current tense. Come with me, then, to a Far Side that depicts Jesus brewing a cup of coffee and thinking
to Himself, "I feel like I've been dead for 3 days." If you were to ask that Jesus, "Hey, when did you get nailed to the cross?" He would most
probably say, "Two days ago." (Actually, He would most probably talk about something completely different, but let's run with this for now...). One
wouldn't say, "oh, about 39 hours 13 minutes and 54.332 seconds ago."
So, in closing, the next post will have a fun exchange of dialog to try to clear it up a little more easily
