For the denominations of the world to be right, the bible has to be wrong and contain errors. The opposite is true for the church of Christ. The only way anyone can disprove the doctrine of the church of Christ is to claim that the bible itself contains errors.
If you are a Catholic, the only way you can claim to be right is to claim that the bible we have is not complete. Therefore, they add to the bible their own catechisms and man authored doctrines. They even have their own bible. This is why they have Popes, Cardinals and Nuns, for the bible speaks nothing concerning any of these.
If you are a Baptist, the only way to claim you are right is to claim that the bible is not sufficient. Therefore, they add to the bible with their man written manuals to govern their ever changing beliefs. This is why they have women deacons and preachers, and doctrines such as ‘Faith Only’ and ‘Once Saved, Always Saved’. When they do go to the bible, they make sure to twist the Word of God to fit their man made doctrines.
If you are a Church of Christ, the only way you can claim to be right is to claim that the bible is God inspired, is perfect, and is all sufficient. 2 Tim 3:16,17 ff; Ps 12:6; 2 Pet 1:3 They must claim to speak where the bible speaks and remain silent where the bible is silent. 1 Pet 4:11 Therefore, they can quote book, chapter and verse to prove that the gospel they proclaim is truth. 1 Thess 5:21 f; Jn 17:17 This is how they can claim that the doctrine they teach is from Christ and his apostles. Acts 2:42 f; 2 Jn 9 This is how they know that they are absolutely right! The only way to say that they are not right is to quote those catechisms, church manuals, denominational bibles, and man made doctrines.
Sadly, many in the churches of Christ have forgotten what made them right with God. Sadly, many don’t speak the oracles of God. Many churches of Christ call all those who do, ‘Legalist’. This is what denominations used to call the churches of Christ concerning the gospel.
Conclusion: Consider this, when you stand before God Almighty to be judged, as we all will one day soon, do you want your soul to stand in the wisdom of men or or God? 1 Cor 2:5 The Pope says your baptism as a baby will save you. Baptist preachers will tell you to accept Jesus as your personal savior and you will be saved. Jesus and his apostles taught all faithful confessed believers who have repented and were baptized into the death of Christ shall be saved. Rom 10:10 ff; Acts 2:38; Rev 2:10 Jesus and Paul both stated that we shall be judged according to God’s Holy Word. Jn 12:48 f; Rom 2:16 There will be no catechisms, no church manuals, and no Catholic or Mormon bibles to determine whether your soul will suffer eternally in hell or be with God forever. No! Only God’s Word will judge you. Therefore, don’t you think it’s time to get in align with God’s Word? It’s time to face it, the bible is flawless! Prov 30:6 Therefore, obey it as is, and whatever you do, don’t change a thing! Gal 1:6-9 f; 1 Cor 4:6
