In my experience, coming from a catholic upbringing, every catholic in my family, who I knew, friends of family etc,etc have had very little interest in Jesus Christ. I have seen drug attics, people addicted to pornography, adultery, drunkenness, greed, sexual immorality, deceit, anger, lukewarmness, and straight ungodly slave to sin lives be changed from the inside to being kind, faithful, righteous, loving, sober, and truthful people from the heart. And in my experience of Protestantism, I saw thus plenty. I’ve seen Christians excommunicated for failing to live a repentant lifestyle and I’ve seen people who worship the lord day and night, who would die for the world. Whereas in Catholicism I’ve seen people who have a hohum attitude about Christ, no faithful sharing of Christs broken body to the lost world, people who are violent and so enslaved to sin that they think its OK. So protestants who are enslaved to christ who would die for the gospel need more prayers than a catholic who lives in sin and has no love for christ?
Maybe if I see this inbcatholicism I would think different. But to this day my huge family are drunks, yet all go to mass and are friends with the priest. Christ is angry at that.
This does not alleviate the guilt of all the schismatics and heretics in the world. But you know what, you had heretics back in the day and so now. In fact Paul said they would come out from among the church and he told Timothy to gaurd the faith because of the possibility if falling away as Paul himself saw in his own co-workers whom he delivered tobsatan or if they loved this present world.
