Why would you be “unsure that it is true”?
Have you gone to Mass every Sunday for 3 years to find out?
The Sunday Masses are in a three year cycle—years A,B, and C, . In addition, in the daily Masses, the Scriptures are in a 2-year cycle—Year I and Year II. The Sacred Scriptures, in the 3-year Sunday cycles and the 2-year daily cycles, are thoroughly covered.
In addition, the readings of the Sunday Masses and the daily Masses are matched thematically. They are not loosely thrown together. For this reason, many Catholics are often very familiar with Scriptural texts and phrases, not any more by chapter and verse, than also by similarity of theme.
But not to worry, I have been selected to know Yah'shua and serve Him. I know Him much better now that I have read all of His Word.Yes i have and that is why I doubt the statement.
shalom b'SHEM Yah'shua
