Fortunately, a "church leader" does not define the congregation. Just as there are among non-Catholics, there are Catholic believers who do not follow a leadership's false teaching, and who are true believers, trusting in the blood of Christ to cover their sins and in His resurrection to bring them newness of life.
It is a grave error to assume what comes out of the mouth of the leadership is in the hearts of those who belong to the church he leads. Though it appears many in Ireland do, indeed, follow their leader out of what is in their hearts, there are millions who do not. I know one such man, and he assures me there are many. But he will not leave the Catholic Church, because, as he put it, "If we who believe leave, who will teach the others?"
I would urge all Christians not to attempt to judge the believers in the Catholic Church by what their leadership says, or what their doctrine teaches.
Talk to the Catholics you know. Find out what they believe. If they are in agreement as to who Christ is, what He has done for us, and how that plays out in their lives, then embrace them. They are brothers and sisters.
If the are not in agreement, lovingly and gently put the truth before them and let the Holy Spirit work on and in them to bring them to understanding, and where necessary, salvation.
We need to stop slaying our misguided, wounded and strayed, and start working together against the real enemy in this world.
