So tell me, if I grew up in a Baptist church and believed my whole life in what they taught what do you think will happen to me on Judgement day? Since the Catholic church is the ONLY true church according to you, did my Baptist church, who taught all things Biblical, lead me to a path away from Jesus where He will end up rejecting me? If not...then what DOES it matter? If I am a child of God saved by the Lord himself through belief, faith, repentence and accepting His spirit into my heart what does it matter if I even ATTEND a church???
I think it only matters, in that a good church, is a good place for learning things like discipleship, evangelism, and is also a good place to fellowship with like minded believers. Being a member of ANY church, will not get anyone saved, and won't keep anyone saved. That is just the cold hard fact of life. I know many do not accept that, but that is not my problem.
We are told to gather together. The New Testament model is to do so.
While there can be times when you cannot physically go to a church, as i myself right now, it is not normative not to be part of a church. We are saved by grace as contrite damned+destitute sinners coming to Christ, trusting Him to save us on His blood-expense and credit, which faith is counted for righteousness, (Rm. 3:8-4:7ff)
However, the only faith is such is that which effects the obedience of faith, which confesses Christ in word and in deed. (Mt. 10:32; Rm. 10:9,10)
Which is shown in worship, devotion, prayer and sanctification and service. Thus those ,
that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers. (Acts 2:41-42)
When you were born again, then you were baptized into the body of Christ, (1Cor. 12:13) which in Scripture is manifest in organic communities. For Christ did not build some well running parts, but a church upon Himself, with which to prevail against the gate of Hell. (Mt. 16:18; Eph. 2:20)
And which army is not a bunch of isolated parts: "For the body is not one member, but many." (1 Corinthians 12:14) "Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. (Hebrews 10:25) By this shall all men know that ye are my disciples, if ye have love one to another. (John 13:35)
Thus the normative means of expressing faith in Christ is by being part of a community, worshiping and praying together, in addition to what we do by ourselves.
Judgment is for God but Christ gave the Great Commission to St. Peter and his successors to teach ONE truth. These teachings tell us how we get to God in union with his Mother, the saints and martyrs. What you think your “Baptist Church taught you all things Biblical,” is no different than what Rev. Moon tells the congregants of his Church, or what the Anglican Church teaches, or Lutherans, or the corner street Four Square First Church of Calvary or whatever they want to call themselves teach. I am sure your Baptist Church does not believe in the “Holy Eucharist” based on the Scriptural reading “as interpreted by the Catholic Church,” that unless you eat of My Flesh and drink of My blood you shall not have life everlasting.
