As far as the Catholic Church is concerned, humans have not been gifted with the ability to determine when God is acting or not and with whom. In line with the Scriptures, the Catholic Church recognizes that God interacts with all peoples, those who believe in God and those who do not.
“Does God belong to Jews alone? Does he not belong to Gentiles, too?” asked St. Paul at Romans 3.29. He answers his own question by saying, “Yes, also to Gentiles.” The Church accepts the truth of Scripture that teaches that God is not bound by denominational lines, divisions, and differences. Even to those who may not worship according to the prescriptions of what some might claim is “acceptable religion,” God has born enough witness in creation and in the natural law available to all to come to some knowledge of Him and His truths.—Romans 1.20, 21; 2.14, 15.
Jesus stated that God “makes his sun rise on the bad and the good, and causes rain to fall on the just and the unjust.” (Matthew 5.45) In line with all of this, who are we to say which people have not been gifted with the Holy Spirit and who has? Didn’t God teach St. Peter that even he should not come to his own judgment in this matter? God grants the Spirit according to His will, not yours, not mine.—See Acts chapter 10.
While I cannot speak for others, it would seem to me a fool who thinks he has a handle on God and that they possess enlightenment that can verify when God acts and when God does not, and how. Truly, have any of us the means to prove and guarantee that we have such insight? Have we never read the Scripture wherein God asks: “Will one who argues with the Almighty be corrected? Let him who would instruct God give answer!” And then again: “Gird up your loins now, like a man. I will question you, and you tell me the answers! Would you refuse to acknowledge my right? Would you condemn me that you may be justified?”—Job 40.1-8.
I think only God can answer. Some might believe they can say for sure, but I can only speak for myself when I say God has asked neither for my opinion or my instruction on this matter that I might argue that I have the answer and can say for sure.
