Lord Rama is often known as the supreme being according to Vaishnavism. This is evidenced by many scriptural refereces:
Brahma in Valmiki Ramayana 6.117.31-32 calls Rama the first/primeval and eternal lord
Shiva says "When that Supreme being of Vedas born as son of Dasratha (Śrī Rām) in Ayodhya, that time all Vedas manifested themselves through the mouth of sage Valmiki..... directly as Ramayana. Therefore .... there is no doubt that Sri Ramayana is the Vedas itself" (Mangalacharan of Valmiki Ramayana; & Agastya samhita)
Rama is Para-Brahma and supreme austerity, and Rama is the Supreme Essence and Brahma Taraka. (Rama Rahasya Upanishad 1.6)
रमन्ते योगिनोऽनन्ते नित्यानन्दे चिदात्मनि । इति रामपदेनासौ परंब्रह्माभिधियते ।। (- श्रीरामपूर्वतापनीय उपनिषद १।६ ) or The Parabrahman which is infinite, immeasurable, pure consciousness, eternal and forever blissful, on which Yogis devote themselves and meditate continuously; that Parabrahman itself is denoted by word ‘Rāma’ directly in Abhidhaa Vritti. (Shri Rama-PurvaTapnIya Upanishada)
राम त्वं परमात्मसि सच्चिदानन्दविग्रहः॥ इदानीं त्वां रघुश्रेष्ठ प्रणमामि मुहुर्मुहुः। (शुक्लयजुर्वेदीय मुक्तिकोपनिषद् 1/4,5क) “O' Śrī Rāma! You are the Supreme Being (Paramatma), The Parambrahman, of the nature Sat, Chit and Ananda! I pay my obeisance in your lotus feet again and again.” (Muktika Upanishada 1)
His Vishwaroopa is discussed in Adbudh Ramayan, Sri Ramcharitmanas 1.202.1,2 and even in the Mahabharata:
“Behold me now in my native form: I give thee sight.' Then Rama of Bhrigu's race beheld in the body of Dasaratha's son the Adityas with the Vasus, the Rudras, the Sadhyas with the Marutas, the Pitris, Hutasana, the stellar constellations and the planets, the Gandharvas, the Rakshasas, the Yakshas, the Rivers, the tirthas, those eternal Rishis identified with Brahma and called the Valkhilyas, the celestial Rishis, the Seas and Mountains, the Vedas with the Upanishads and Vashats and the sacrifices, the Samans in their living form, the Science of weapons, O Bharata, and the Clouds with rain and lightning, O Yudhishthira! And the illustrious Vishnu then shot that shaft.” (Mahabharata, Vanaparva, Tirthyatra Parva, section XCIX)
But Bhagavad Gita 11.47 says his Vishwaroop is being shown for first time ever !! And then we see in Bhagavad Gita that Krishna says that he is only Rama among warriors and Rama is mentioned along with lion, Garuda, Prahlada, wind and Ganges!! Like he is almost degrading Rama to just a warrior and a small portion of himself:
पवनः पवतामस्मि रामः शस्त्रभृतामहम्। ।10.31। or Among the purifiers (or the speeders) I am the wind; RAMA AMONG THE WARRIORS AM I
How can Krishna's words and everything else be reconciled? Even in Krishna Upanishad Rama tells that he will reincarnate as Krishna.
Can these 2 different parts (Vishwaroop & warrior part) be considered interpolations in Bhagavad Gita? EDIT - It seems there is an interpolation in B Gita 10.37 (based on answer) because it says Vrishinam in one version and Yadavam in another!
