咁就係視乎你講啲神係點。例如，好簡單，喺我眼中，神唔係三位一體。都唔係猶太教同伊斯蘭教個種Absolutely Monotheism。如果你單係用咁嘅角度去睇，就會得出大家嘅神唔係同一神。
但轉個方向諗，其實係可以任何宗教都出自同一位神，但唔同嘅文化、傳統、歷史事件或人啲干預而令人對神嘅理解出現唔同程度嘅偏差。喺討論呢樣嘢前，畀你睇下LDS正式立場，呢段係1978年嘅啟示節錄落嚟。雖然唔係正式經文，但都算係被視為恆常教義同正式啟示嚟。
Statement of the First Presidency regarding God's love for all mankind - 15 Feb 1978
Based upon ancient and modern revelation,
The Church of Jesus Christ of Latter-day Saints gladly teaches and declares the Christian doctrine that all men and women are brothers and sisters, not only by blood relationship from common mortal progenitors, but also as literal spirit children of an Eternal Father.
The great religious leaders of the world—such as Mohammed, Confucius, and the Reformers, as well as philosophers including Socrates, Plato, and others—received a portion of God's light.
Moral truths were given to them by God to enlighten whole nations and to bring a higher level of understanding to individuals.
The Hebrew prophets prepared the way for the coming of Jesus Christ, the promised Messiah, who should provide salvation for all mankind who believe in the gospel.
Consistent with these truths, we believe that God has given and will give to all peoples sufficient knowledge to help them on their way to eternal salvation, either in this life or in the life to come.
We also declare that the gospel of Jesus Christ, restored to His Church in our day, provides the only way to a mortal life of happiness and a fulness of joy forever.
For those who have not received this gospel, the opportunity will come to them in the life hereafter if not in this life.
Our message therefore is one of special love and concern for the eternal welfare of all men and women, regardless of religious belief, race, or nationality,
knowing that we are truly brothers and sisters because we are sons and daughters of the same Eternal Father.

我以LDS眼光用返你上面提到嘅宗教咁整個好實在嘅歷史例子解釋（當然我預咗其他人負皮我）：
猶太教嘅出現係因為猶太人偏離咗神，神召摩西
復興真理。神將福音圓滿嘅真理（圓滿唔係全部，因為只有神先知全部真理）交畀摩西，
當中包括摩西唔需要靠前人嘅著作，就可以直接接收神啟示摩西去寫返以前失去咗嘅知識（亞當、以諾、挪亞等經文），教導有關耶穌基督會嚟到世界去贖罪，整套摩西律法其實就係提高人嘅道德標準，同埋指向基督。等當耶穌真係嚟時，猶太人會認得佢。
但約公元前700～600年，猶太教被Deuteronomist（申命記編輯者派系）嘅人所作出嘅權力鬥爭修改咗好多舊約聖經。統一化咗猶太教、令整個宗教傾向當年嘅猶太王（呢部份其實已經有好詳細嘅學術研究，算係無可質疑嘅歷史同學術睇法嚟）。所以猶太教就喺呢到開始變咗質，失去圓滿嘅真理，但唔係完全無晒真理。
基督教嘅出現就係猶太教偏離後，耶穌基督親自嚟
復興圓滿嘅真理。耶穌解釋返好多猶太教當時嘅錯誤認知，組織咗教會，召喚使徒等等。
耶穌死後，使徒們已經睇到人又開始偏離，甚至作過預言會有叛教發生（使徒行傳 20:28–30，提摩太後書 4:3–4等等）。
到天主教，先講明，我好尊重天主教，我時不時會去天主教堂坐同祈禱。如果我嘅教派係錯，咁天主教就會係我唯一覺得有機會係真嘅教派。我都見有好幾位天主教徒喺到，所以講聲先。
天主教係啲人喺使徒們死後，教會失去咗使徒權柄後嘅產物（當然我明天主教徒眼中佢哋無失去過，如同正教眼中個使徒權柄喺正教到，咁如果我信天主教有個權柄我就做咗天主教徒啦，正因為我喺歷史上睇，我覺得無嘅機會大過有）。佢哋好崇高咁keep住咗教會嘅傳統，但失去權柄後就不免增加人為錯誤嘅機會。
當中最大嘅錯誤就係喺無使徒權柄嘅情況下去解釋父神、子神、聖靈嘅關係，亦係講緊三位一體嘅教義。喺呢到人偏離咗神，得到咗對神錯誤嘅理解。
伊斯蘭教，用返上面引用段英文Statement，基本上就係綠字嘅解釋。神不論地域、文化 都會將佢嘅光畀人。雖然伊斯蘭教無圓滿嘅真理，喺我LDS眼中都唔算係一種
復興，但都可以講係嚟自同一位神。
我唔會份識太多伊斯蘭教，但如果你想好深入咁以一個非常學術嘅LDS角度去睇，我會推薦你睇Muhammad, Prophet of God，by Daniel C Peterson - bachelor's degree in Greek and philosophy, Ph.D. in Near Eastern Languages and Cultures, professor of Islamic Studies and Arabic.
簡單講，我哋接受穆罕默德可以係神所召喚嘅「prophet」with lower case p，即係都係神感召，但無我之前同你一直討論嘅權柄。
新教，神感召新教運動興起者，令人脫離中世紀，步入文藝復興。令人喺宗教上有覺醒。都係嚟自同一位神感召，但無權柄。所以同伊斯蘭教一樣，唔算係
復興。
最後LDS，因為人由使徒而後已經又偏離咗神，神召約瑟斯密為先知、給予佢權柄、復興咗圓滿真理。
正如摩西唔需要前人著作咁寫返以前嘅經文，約瑟都接收啟示寫返好多失去咗嘅經文。將整個救恩計劃，神嘅本質嘅知識再復興返嚟。
其實由頭到尾，你會見到呢啲所有宗教都係出自同一位神。只係每次人都偏離咗，咁你見到嘅都係已經偏離咗嘅xx教，而唔係最初嘅xx教。如果你有時光機返去睇返最初嘅猶太教、基督教同埋而家嘅LDS，就會睇到全部教緊一樣嘅神。
最後，猶太人嘅特殊地位唔係出自佢哋嘅血統，而係因為佢哋守嘅約。神同人立約，只要人喺最低限度遵守呢個守（亞伯拉罕之約）。個特殊地位係嚟自猶太人同神立嘅約。如果你都一樣同神立約，就會被算作神啲約民。個地位同猶太人係一樣。重點喺個約到，唔係血統到。
創世記:12:2 我必叫你成為大國，我必賜福給你，叫你的名為大，你也要叫別人得福。
3 為你祝福的，我必賜福與他，那咒詛你的，我必咒詛他，地上的萬族都要因你得福。
好長，希望答到你
