This is not the case.
Protestants did not remove seven books from the Old Testament and neither did the Catholic Church add them, which Protestants often accuse the Church of doing.
The Church canon of the Old Testament, used the Greek Septuagint version of the Old Testament, which was for Greek speaking Jews. The Septuagint, included the seven books we have. The Church continued to use this version and still does today.
After the Reformation, protestants began using the Hebrew Version of the Old Testament which did not include the 7 books that the Septuagint had.
So, it wasn’t that they removed books, but rather, they used a different Old Testament translation.
One reason they did this is because Jews had rejected the Septuagint as an acceptable version of the OT, way back after the destruction of the Temple by the Romans. The Rabbinical School at Jamnia, wanted to distance Jews from Christianity, so rejected the Septuagint and claimed that it was never an official translation. This fell apart after the Dead Sea Scrolls were discovered and the Septuagint was in that discovery as well as the Hebrew translation. There were also other writings, supporting the fact that the Septuagint was an accepted translation by Jews during Jesus time.
Lastly, 80% of the OT references in the NT are found in the Septuagint.
