CC Ādi 1.31

sakala vaiṣṇava, śuna kari’ eka-mana
caitanya-kṛṣṇera śāstra-mata-nirūpaṇa
Word for word: 
sakala — all; vaiṣṇava — O devotees of the Lord; śuna — please hear; kari’ — making; eka-mana — rapt attention; caitanya — Lord Caitanya Mahāprabhu; kṛṣṇera — of Lord Śrī Kṛṣṇa; śāstra — scriptural reference; mata — according to; nirūpaṇa — decision.
I request all my Vaiṣṇava readers to read and hear with rapt attention this narration of Śrī Kṛṣṇa Caitanya as inculcated in the revealed scriptures.

Lord Caitanya is the Absolute Truth, Kṛṣṇa Himself. This is substantiated by evidence from the authentic spiritual scriptures. Sometimes people accept a man as God on the basis of their whimsical sentiments and without reference to the revealed scriptures, but the author of Caitanya-caritāmṛta proves all his statements by citing the śāstras. Thus he establishes that Caitanya Mahāprabhu is the Supreme Personality of Godhead.
