True & those who **study **those “private” revelations that the Church APPROVES are wise too.
There can be extremes on both ends of this issue. People can base their entire faith upon some miracle, others can completely reject all of them & try to live their lives without any help other than Scripture.
The Protestant “reformers” were the first to reject all private revelation, it was a MUST for them because all private revelation & miracles that occured prior to Martin Luther had confirmed that the Catholic Church was the one, true Church founded by Christ & that He still spoke to the world through His Church. Protestants could not take the chance that any new revelation, such as those at Fatima would be binding on all Christians. One thing they could not refute was Scripture— "Do not quench the Spirit.
Do not despise prophetic utterances. Test everything; retain what is good" (1 Thess. 5:19–21).
The "reformers’ denials of all new revelation led people to become confused about the difference between private & public revelation. (I still cannot figure out why Fatima is considered private revelation when the spinning sun was witnessed by 70,000 people

)
This attitude toward miracles has been changing during the 20th century. After all, we have Mohammed, the Mormons & the Charismatic movement. In the latter, with it’s emotional approach to faith, almost EVERYONE claims to have spoken in tongues, seen Christ, spoken with St. Peter & having been knocked to the ground by the Holy Spirit.
In short, I think it’s the responsibility of all Catholics to search & study the revelations that have the appoval of the Church. To do less, is self-defeating.
