That is painting with a VERY broad brush. It seems you are quite biased towards the Mormons and JW’s. We are called to not be lukewarm for our faith…Rev 3:16 “So, because you are lukewarm, and neither cold nor hot, I will spew you out of my mouth.” I take my faith in Christ VERY seriously.
I have no doubt there are many Christians in the JWs as well as the Mormons. In fact I meet very often on Saturday with two JWs who visit me often and discuss Scripture. Eventually I will get them to accept the truth.
The reason we worship on Sunday and not Saturday is because our Lord and Savior Jesus Christ was resurrected on Sunday. Wouldn’t it make sense to worship the risen Lord on the day He was risen?

For Catholics though, Mass is every single day. If you have the time, you could attend Mass every day of the week even though Holy Obligation is only on Sunday because of the aforementioned reason. But I am sure you would like some scripture to go along with this reasoning and here ya go! Acts 20:7 “On the first day of the week, when we were gathered together to break bread, Paul talked with them, intending to depart on the morrow; and he prolonged his speech until midnight.”
**You are incorrect when you say Christ was resurrected on Sunday. He was found to be gone at daybreak on Sunday but according to the Bible, he was resurrected on what we would call Saturday night—just after the Sabbath ended at 6 PM.
If you will read the Bible, you will find that Christ always observed the Sabbath, not Sunday as did the apostles, even after the resurrection. Paul was in the temple every Sabbath as was Peter. There is no record of any of them not observing the Sabbath.**
For one to be a Christian, you should be baptized in trinatarian form…Look at Matthew 28:18-20…Believe Jesus Christ is God…John 3:16…Repent from your sins…Luke 13:3…and confess Jesus as Lord Romans 10:9-10. Faith alone doesn’t cut it…I’m not implying that you believe in that but for the benefit of those out there that do…Even St. Paul wasn’t sure he was saved…He said, Php 2:12 “Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling.”
I can give you several Scriptures that say that faith alone and nothing is necessary for salvation. There are no verses that say that works are necessary—none.
It isnt as much that we have to rely on the church to tell us what it says. It is just that there are so many different interpretations out there that we need to know what the TRUE interpretation of certain verses are and that can only be found in the church that was given the Authority by Jesus Christ Himself (Matthew 16:18).
Anytime any church strays from Scripture, then it is teaching falsely. Scripture is not difficult to interpret. It usually interprets itself, one only has to look for the truth to find it.
Show me at least one inkling of historical proof that “everything was fine…then Rome got too involved.” Peter was given the Keys and then eventually He went to Rome to help Paul preach to the Gentiles. Unfortunately they both met their demise in Rome but, from that time forward, all the Popes from St. Peter to the present Pope have all resided in Rome. Maybe you can go into more detail what exactly you mean by Rome getting too involved as well.
**There is no record of Peter ever being in Rome. Perhaps he was but we have no historical record of him ever being there. And as for the popes, for 70 years, there was no pope anywhere, and for 40 years the pope was in France and at one time there were three popes, so there is no succession of popes. Certainly not from Rome. Even the RCC can’t agree on the first few lists of popes.
What I mean by Rome getting involved is that when Constantine started the state control of the church, he introduced paganistic rituals into it. In addition, from his time on, many false teachings started being introduced into the church, such as: purgatory, Mariolatry, prayer to the dead, and many more non-Biblical teachings. The early church leaders such as: Clement of Rome, Clement of Alexandria, Barnabas, Mathetes, Polycarp, Ignatius, Irenæus, and many others, would cringe if they could see what the RCC is like today.**
Have fun at the beach. I await your response upon your return. God bless.
**It was a great time at the beach—it always is and we enjoy it. We should just stay at the Condo all summer but other family members want to use it as well, so we indulge them.
In Christ…CR**
