In Mt 5:18 Jesus promised that no letter of the Bible (the Law) should be lost. In other places, God made it clear that He would punish falsification of the Bible (Rev 22:18-19, Gal 1:6-10; Luke 17:1-3; Matt 18:6-7; Mark 9:42). Throughout the centuries until today, the resurrection of Jesus was documented "on a Sabbath morning" or "on one of the Sabbaths" (there are 3 Sabbaths on the Passover feast, see image) in many languages. Many German Catholic Bibles even spoke of "a Saturday morning" when the women went to the grave (Link1, Link2). Sometimes the word "one" was translated as "first". Although this is not literal, it is correct in content, since this "first Sabbath" (Mark 16:9) is the first in a series of seven Sabbaths up to Pentecost. Therefore this phrase “on the first of the Sabbaths” is also correct.

Here are some examples of the first Bibles in 7 languages: 

1. Basic Greek text

2. Latin Vulgate 

3. German Luther Bible and among them the Catholic counter Bible of Emser 1527

4. English Coverdale Bible 1535, the first complete printed English Bible

5. first Spanish NT by Enzinas 1543

6. Italian Brucioli Bible 1530

7. Swedish Gustav Vasa Bible 1541

As can be clearly seen: We are not talking here about a new doctrine or the opinion of a Christian splinter group or a religious sect. No, we are talking about ancient Christian basic knowledge, which has always been found in many old Catholic bibles and in the bibles of kings. There are many free facsimiles that irrevocably confirm all that has been said here.
