Yes, there are a huge number of Catholics in the world. We already know that. I believe many of them are saved, however, just being a Catholic does not mean a person is saved. We have discussed how to get saved on this forum many times. Catholics have to get saved the same way any other person has to get saved. Belonging to a certain group is not a guarantee of salvation no matter how large that group is.
We also know that we have many in our government who are corrupt. Yes, that means they could have something to do with the cover up. Many Christians are praying for our government. I believe this corruption will be exposed in time because of all the prayers going up for our country.
