....But scripture is not to be used to bash other Christians which do include Catholics.
Who is “bashing other Christians” around here? Do you think that reproving, rebuking, or exhorting are bashing? If you feel bashed upon, then find the scripture that supports your particular viewpoint and we’ll study it together to find the truth. That is different than feeling bashed on because you don’t care for what is being told to you.
What makes someone a Christian?
Is it a very particular belief, or is it the result of baptism and the following of very specific actions?
The point I'm getting to is in my understanding of Scripture what makes you a Christian is believing The Gospel. There are other churches that claim to believe The Gospel but they add to it, or don't acknowledge who Jesus Christ is. Even though they claim to be Christians Born Again Christians won't acknowledge them as such. We don't do this because of hatred. We do this because Truth matters.
Showing someone where they are in error using Scripture is NOT “bashing” anyone.
As your premise is presumptuous so is your conclusion. There are RCs here who do not consider us Christian, while by their Rome-centric preaching of an elitist church which has historically often said the same, and of whom we realize no basic fellowship in Christ with, we must conclude most RCs have never realized a day of salvation, with its profound changes in heart and life.
Which is a fruit of her doctrine. Rome in particular (as the church taking up the most space on the broad way to destruction) is most manifest as standing in critical and overall contrast to the NT church. Which church, as manifested in Scripture,
1. Was not based upon the premise of perpetual assured infallibility of office as per Rome, which has presumed to infallibly declare that she is and will perpetually be infallible whenever she speaks in accordance with her infallibly defined (scope and subject-based) formula, which renders her declaration that she is infallible, to be infallible, as well as all else she accordingly declares.
2. Never promised or taught a perpetual assuredly infallible magisterium was necessary for preservation of truth, including writings to be established as Scripture, and for assurance of faith, and that historical descent and being the stewards of Scripture assured that such had assured infallibility.
3. Never was a church that manifested the Lord's supper as being the central means of grace, around which all else revolved, it being “the source and summit of the Christian faith” in which “the work of our redemption is accomplished,” by which one received spiritual life in themselves by consuming human flesh, so that without which eating one cannot have eternal life (as per RC literalism, of Jn. 6:53,54). In contrast to believing the gospel by which one is regenerated, (Acts 10:43-47; 15:7-9; Eph. 1:13) and desiring the milk (1Pt. 2:2) and then the “strong meat” (Heb. 5:12-14) of the word of God, being “nourished” (1Tim. 4:6) by hearing the word of God and letting it dwell in them, (Col. 3:16) by which word (Scriptures) man is to live by, (Mt. 4:4) as Christ lived by the Father, (Jn. 6:57) doing His will being His “meat.” (Jn. 4:34) And with the Lord's supper, which is only manifestly described once in the life of the church, focusing on the church being the body of Christ in showing the Lord sacrificial death by that communal meal.
4. Never had any pastors titled "priests" as they did not engage in any unique sacrificial function, that of turning bread into human flesh and dispensing it to the people, or even dispensing bread as their primary ordained function, versus preaching the word. (2Tim. 4:2)
5. Never differentiated between bishops and elders, and with grand titles ("Most Reverend Eminence," “Very Reverend,” “Most Illustrious and Most Reverend Lord,” “His Eminence Cardinal,” “The Most Reverend the Archbishop,” etc.) or made themselves distinct by their ostentatious pompous garb. (Matthew 23:5-7) Or were all to be formally called “father” as that would require them to be spiritual fathers to all (Mt. 23:8-10 is a form of hyperbole, reproving the love of titles such as Catholicism examples, and “thinking of men above that which is written, and instead the Lord emphasizes the One Father of all who are born of the Spirit, whom He Himself worked to glorify).
6. Never required clerical celibacy as the norm, (1Tim. 3:17) which presumes all such have that gift, (1Cor. 7:7) or otherwise manifested that celibacy was the norm among apostles and pastors, or had vowed to be so. (1Cor. 9:4; Titus 1:5,6)
7. Never taught that Peter was the "rock" of Mt. 16:18 upon which the church is built, interpreting Mt. 16:18, rather than upon the rock of the faith confessed by Peter, thus Christ Himself. (For in contrast to Peter, that the LORD Jesus is the Rock (“petra”) or "stone" (“lithos,” and which denotes a large rock in Mk. 16:4) upon which the church is built is one of the most abundantly confirmed doctrines in the Bible (petra: Rm. 9:33; 1Cor. 10:4; 1Pet. 2:8; cf. Lk. 6:48; 1Cor. 3:11; lithos: Mat. 21:42; Mk.12:10-11; Lk. 20:17-18; Act. 4:11; Rm. 9:33; Eph. 2:20; cf. Dt. 32:4, Is. 28:16) including by Peter himself. (1Pt. 2:4-8) Rome's current catechism attempts to have Peter himself as the rock as well, but also affirms: “On the rock of this faith confessed by St Peter, Christ build his Church,” (pt. 1, sec. 2, cp. 2, para. 424) which understanding some of the so-called “church fathers” concur with.)
8. Never taught or exampled that all the churches were to look to Peter as the bishop of Rome, as the first of a line of supreme heads reigning over all the churches, and having the last word in questions affecting the whole Church.
9. Never recorded or taught any apostolic successors (like for James: Acts 12:1,2) after Judas who was to maintain the original 12: Rv. 21:14) or elected any apostolic successors by voting, versus casting lots (no politics). (Acts 1:15ff)
10. Never recorded or manifested (not by conjecture) sprinkling or baptism without repentant personal faith, that being the stated requirement for baptism. (Acts 2:38; 8:36-38)
11. Never preached a gospel of salvation which begins with becoming good enough inside (formally justified due to infused interior charity), via sprinkling (RC "baptism") in recognition of proxy faith, and which thus usually ends with becoming good enough again to enter Heaven via suffering in purgatory, commencing at death.
12. Never supported or made laws that restricted personal reading of Scripture by laity (contrary to Chrysostom), if able and available, sometimes even outlawing it when it was.
13. Never used the sword of men to deal with its theological dissenters.
14. Never taught that the deity Muslims worship (who is not as an "unknown god") is the same as theirs.
15. Never had a separate class of believers called “saints.”
16. Never prayed to anyone in Heaven but the Lord, or were instructed to (i.e. "our Mother who art in Heaven") who were able to hear and respond to virtually unlimited prayers addressed to them (a uniquely Divine attribute in Scripture).
Would you have also said that to Jesus who used scripture to correct teaching that was in error?
Matthew 22:29 Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.
Matthew 22:31 But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying,
When correcting people Jesus always used scripture.
Mark 12:10 And have ye not read this scripture; The stone which the builders rejected is become the head of the corner:
God said scripture would be the everlasting witness.
Isaiah 30:8 Now go and write down these words. Write them in a book. They will stand until the end of time as a witness
Jeremiah 30:2 Thus speaketh the LORD God of Israel, saying, Write thee all the words that I have spoken unto thee in a book.
God commanded that His word be written down and Jesus used that written word to correct and admonish people. Only those who are being corrected by it would consider it bashing.
