About 1 year ago (sometime in May or June) I was given a sermon/lecture concerning Roman Catholicism focusing on the Pope and the Papacy. But before I talk a little bit more about this lecture, let me bring forward some of my background as it relates to this issue.
I grew up in a Christian home where we attended an Assemblies of God church. When I was in the eighth grade (or so), my parents decided to seek a better church for us to fellowship and worship in. Over the next two (or so) years we went to a few different churches, but I never felt comfortable with them. Finally, we settled in at a local church (LeMars Bible Church, called LBC), and my parents have been there ever since.
Over the course of my life, I have attended a Pentacostal church (Assemblies of God), a charismatic church (Cornerstone Faith Center - I never liked this church because even as a child I could sense the "ickiness" of the health and wealth gospel), a non-denominational Baptist-style church, and now I attend a very good fundamental Baptist church. I bring up this history for a few reasons.
First of all, my theological formation started out more on the Pentacostal and Arminian side and has developed (through study and agony) to be conservative, Baptist, and Calvinistic. So the first reason is to show the diversity of my exposure to various doctrines and traditions.
The second reason that I bring this up is that even though the various churches had different doctrines on Spiritual gifts, doctrines of the roles of men and women, different worship style, various preaching styles, and other issues, one thing remained consistent. These churches agreed on the essential truths of scripture - the Trinity, God the Father, God the Son, God the Holy Spirit, the inerrancy and infallibility and sufficiency of the Bible, and the message of salvation - the gospel.
The gospel message that I was given as a small child by Mrs. Sylvia Shultz is the same message that was proclaimed to me at LBC, at Ambassador Baptist Church, and it is the same one that I proclaim. Salvation is by grace alone through faith apart from works in Jesus Christ alone.
As a child (and now as an adult) I have had close friends and family members who were not Christians. Some of them professed to be Christians and even went to churches, some were basically irreligious. I also have and have had family and friends who are Roman Catholic. The gospel message that these people knew (and was established in their confirmation classes) was not the same gospel.
The gospel of Roman Catholicism is as different from the Biblical gospel as that of Mormonism in that they both are false, and they do not save. I say this not as a stick in the eye of a Catholic who might be reading this (although, that is unavoidably going to be the outcome). I say this to make plain that there is no fellowship of the faithful or believers that can exist in any real form between those who confess a biblical gospel and those who confess the doctrines of Rome.
There have been moves recently to reconcile the Protestants with the Catholics which many (on both sides) vehemently disagree with. For, even if traditional Roman Catholics disagree with my conclusion that their system is false (they charge Protestants with being false), they agree that our systems are so vastly different that there is no way to be acceptable to both Protestants and Catholics in any real theological sense.
With that background....
The lecture that I was presented was delivered by John MacArthur. He articulated, very well, in one message some of the very reasons why Catholicism and the true gospel message are not compatible. In fact, he opens his message by saying that if a Roman Catholic hears this message, they will surely be offended. But it is not the purpose of offending people or inculcating "anti-Catholic" sentiment that either he preached this message or that I talk about it here. It is to defend the gospel of Christ, defend Christ Himself, and to call out to those who are lost with the truth.
You can listen to the message as it was played on the Way of the Master Radio program. It is divided up into two parts (the two portions of the show) by clicking below:
For my brothers and sisters who desire to reconcile with the Catholic Church, I hope that this will help articulate or clear up why there can be no "blurring" of the distinctions between Catholicism and true Christianity. For my friends and relatives inside of Roman Catholicism, I hope that God will open your eyes, show you the false system that you are in, and call you out of it.
