Perhaps you could give us some examples of what is found in the Biblical text--which isn't found in the LDS church?
Glad you asked!
Nine Points of the True Christian Church
- The true Christian church teaches monotheism, the belief that only one God exists, and that is the God who we worship (Deut. 4:35,39, 1 Kings 8:60, Isa. 43:10, 44:6,8, 45:5,21,22, 46:9, John 17:3, 1 Cor. 8:4-6, etc.)
- The true Christian church teaches that God is a Trinity. This is simply a recognition that while there only exists one God, that God exists in the form of three different “persons” (ie. “identities”). The Father is God (Matt. 5:16), the Son is God (John 1:1), the Holy Spirit is God (Acts 5:3,4). The term “God” here is not used as a name (for it is not), but simply for the type of being He is (ie. “deity”). God’s name is actually “YHWH”, sometimes called the “Tetragrammaton”, and sometimes used in the form of “Yahweh” or “Jehovah”.
- The true Christian church must teach that God is spirit (John 4:24), and that a spirit doesn’t have flesh and bones (Luke 24:39). Further, Scriptures plainly and repeatedly teach that “God is not a man” (Num. 23:19, 1 Sam. 15:29, Job 9:32). God is invisible (Col. 1:15, 1 Tim. 1:17, Heb. 11:27). Far from God and man being the same “species”, God is Creator, and man the creature (creation) (Gen. 1:27, Eph. 2:10, etc.). Jesus, who is God, took on a body of flesh, and the reason He needed to take on a body is precisely because a physical body is not part of inherent nature of God.
- The true Christian church teaches that salvation is wholly of God, all of grace, and “not by works” (Eph. 2:8-9, 2 Tim. 1:9, Tit. 3:5, Rom. 4:1-5, Rom. 9:11,16, Rom. 11:5-6, etc.). True Christians will do works, but these works are the “fruits” of our salvation, and are the result of a person being saved, not some “requirement” for them to be saved.
- The true Christian church no longer has human “prophets” (Heb. 1:1-2, Luke 16:16-31, Matt. 11:13). Instead of one man speaking for God to the people, God has given all of His people the Holy Spirit (Acts 2:1-19, cf. Joel 2:28-29, Num. 11:29). God now speaks to all of His people directly, and no longer speaks through a secondary person.
- The true Christian church is apostolic, and conforms to the teaching of Christ’s 1st century apostles. There is only one set of apostles, and they are those who qualify according to Acts 1:21-22, being a firsthand witness of Christ’s ministry, death and resurrection. Unless one is 2000 years old, no authentic “apostles” qualify today. The Bible teaches that the church is built on the foundation (laid once) of (Old Testament) prophets and (New Testament) apostles.
- The true Christian church has elders, qualified as per the teachings of Paul in his epistles to Timothy and Titus (1 Tim. 3:2,12, Titus 1:5-6). They are older, more mature Christians (not “teenagers”), men who are monogamously married (“the husband of one wife”), with well-behaved children, and who have demonstrated the ability to run a household well.
- The true Christian church teaches that marriage is a temporary, earthly relationship (Rom. 7:2,3, 1 Cor. 7:39). There is no marriage in heaven (Matt. 22:30). Actually, there is only one eternal marriage, only one “marriage in heaven”, that is taught in the Bible, and that is the metaphorical marriage of the Lamb (Rev. 19:7-9), Christ the bridegroom, and the church, His bride (2 Cor. 11:2)
- The true Christian church must recognize the right of the pastor/teacher/minister to be paid (1 Cor. 9:7-12), and the duty of those who receive spiritual education and encouragement to financially support their teachers (1 Tim. 5:17-18). This principle is taught all the way from the Torah (Deut. 25:4, and in fact goes back to the Israelites financially supporting their priests through their tithes)), confirmed by the teachings of Jesus (Luke 10:7), and continues as an apostolic teaching (1 Cor. 9:7-12, 1 Tim. 5:17-18)
- God is unchanging (Mal. 3:6), He is the same yesterday, today, and forever (Heb. 13:8). He has always been perfect, omnipotent, omnipresent, and omniscient. God has never had to “learn” anything new, as He is omniscient, and knows the end from the beginning (Isa. 46:10). He has never “progressed”, as He has never been anything less than God. He will never “progress”, for He is already perfect and divine.
Mormons generally respond to these questions by ignoring the passages in question and going to their own rehearsed "proof-texts". I hope this is not the tack taken, as that implies a rejection of those Scriptures in question.
I look forward to a thoughtful response.
