Hi Cody,
This isn't going to be too spiritual or educated but, have you ever considered the logistics of 3,000 people being immersed in one day (Acts 3:41)? Let's do some math.
How many fresh air baptisms have you attended? A lot of reformed people have never had that experience. The one I went to about five years ago had seven people getting baptized in a swimming pool.
I pasted the whole Passage below for your convenience.
Acts 2:37-41 ESV
[37] Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?”
[38] And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.
[39] For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.”
[40] And with many other words he bore witness and continued to exhort them, saying, “Save yourselves from this crooked generation.”
[41] So those who received his word were baptized, and there were added that day about three thousand souls.
I have always taken vs. 41 that the baptisms were completed that day. My wife and I attended a pool baptism where seven people were baptized. The seven took about two hours. That's 17± minutes per person which included prayer, testimony, follow by the words and actions of the baptism. Granted, that time could be reduced, but reduced by how much? Maybe there were groups, even whole families dunked simultaneously. But, wouldn't anything faster, or more people at once would present a pretty weird and frenzied service we could hardly recognize.
So how about 3 minutes average per person. Here's the 3rd-grade math.
NOTE:
Days and
Weeks, are based on a 40-hour/5-day week.
3,000 (people) X 3 (minutes) = 9,000 (minutes) = 150 (hours) = 18.75 (8-hour days) = 3.75 (5-day weeks)
At 3 minutes apiece, this baptism would make this among the weirdest baptism ever.
Well, its a theory.
