God hears the prayers of His people.
By asking everyone to come, you imply they are also His people. They are His creatures, undoubtedly, but they are not His people. Atheists who make a mockery of intellect and reason and then themselves by denying Him are not “His people.” They are not “of God,” and therefore cannot be considered as being substantially the same as the “People of God” or God’s People.
That being said, from at least a political perspective what the Pope is doing is very sensical. He is rightly implying that anyone and everyone who personally holds “beliefs” they interiorly believe to be both right and good - in the truest sense - have a very real common cause with, and natural allegiance to, Catholicism. He is implying that our independent beliefs (whether erroneous or correct) ultimately necessitate and require a belief in human dignity, in the existence of objective Truth, and this belief is very much under attack and, therefore, we have common cause to pray together. The Catholic Church prizes and cherishes man’s ability to say, “I believe,” and “We believe” - “the world,” however, most certainly does not or, at least, sickenlingly desires to dictate to us what those beliefs must or should be ; that is, impose upon us a very man-made (as it were, though ultimately, diabolically contrived) religion, one that would most obviously offend the Christian but ultimately those of all other beliefs as well (it being intrinsically necessary for such a thing (man-made and imposed religion) to deny they can find and adhere to that Truth, or that it exists ; hence, the “dictatorship of relativism”).
Satan’s congregation has always used peer pressure, insults, threats, injuries, crimes, murders, lies, slanders, ad infinitum to coerce mankind into a degrading and slavish submission. Our Lord Himself faced this most clearly and poignantly, and all of us have - to greater or lesser extents - faced this kind of cruel, merciless butchery. I believe that in this century more and more the “gloves will be off,” and people will have to come face to face with the reality of evil, and its presense. Being given every right to license and every favour, the evil in this world can only do more evil. We’re coming to a point where it will be laughable for any man to deny the objective existence of Good and also of evil. The extremes will become increasingly witnessed.
