This was on a private website and those giving testimonials were sharing anecdotal evidence of their personal experiences. Why should that have to be scientific?
And this was a Catholic university.
Some forget that catholicism was founded by the ROMANS. It was not founded to teach the truth. It was founded to gain control of the people, not to promote God.
Why else would the church refuse to allow people to read the Bible for themselves. It has to be interpreted through THEIR ‘wisdom’ and teachings.
They fear the Holy Spirit may change hearts and some people may learn that we can truly learn truth only through Him.
