To those who believe the Ascension of Christ was on Sunday....

 "We have also known for a long time that the credulous followers of the egotistical ignoramus who some centuries ago wrote under the pseudonym of Barnabas, regard Sunday as both the first and the eighth day of the week, which has only seven days; but we never before heard that both the resurrection and the ascension of Christ were on the first day of the week. How long will it be before the pleaders for Sunday will claim that every notable event in history took place on that day? Just notice how accommodating that first day is. The resurrection of Christ is generally admitted to have been on Sunday. The writer of the book of Acts says that in a former treatise (the book of Luke) he had set forth all that Jesus began to do and teach until the day in which He was taken up after He had given commandments unto the apostles, 

Acts 1 

3To whom also He showed himself alive after His passion by many infallible proofs, being seen of them forty days. 

Luke records the resurrection and the ascension of Christ, and he says that He was seen alive after His passion forty days. Now let any child that knows the days of the week, and count on its fingers, reckon up and tell on what day the ascension must have been.
• He arose from the tomb very early in the morning of the
first day of the week, so that five full weeks, thirty-five
days, would bring us to the beginning of another first
day of the week.

• The fifth day from that, completing the forty days,
would fall upon the fifth day of the week, or Thursday.
So that, stretching the forty days to their utmost limit, the
ascension of Christ cannot be made to have come later than
very early on Friday morning..." E.J. Waggoner
