For a person who holds such teaching as true, it cannot but have consequences for how that person views Catholicism. This is not just a divergence of views on certain points of Christian dogma. It is much more. It is a sincere belief that the seat of evil abides within the Catholic Church. Not only does it mean that there will be little sympathy for Catholic struggles, it means that in any head-to-head confrontation between Catholicism and other perceived evils such as secular humanism, socialism, communism or Islam, the Catholic Church is the one you root for absolutely last or not at all. Hence, few tears are shed for the present plight of ancient Christian communities in the Middle East, for example.
One should therefore neither expect nor request moral nor material support from such quarters in the present HHS confrontation. That would be naive in the extreme. There's a school of thought, which is not insignificant in size, which says that whatever pain Catholicism experiences, it more than deserves.
Mary will bind both religions together during the tribulation. Faith IN The Lord Jesus Christ is all that matters during this age of grace we are in. Once the rapture happens everything will hit the fan. NOW is the time to accept Christ before it is too late.
