So Caitanya Mahāprabhu is described by Rūpa Gosvāmī: namo mahā-vadānyāya kṛṣṇa-prema-pradāya te. Kṛṣṇāya: and they could detect also, Rūpa Gosvāmī that, "You are no other than Kṛṣṇa. Otherwise who could give kṛṣṇa-prema so easily? If Kṛṣṇa Himself can give it, so You are giving it." So Kṛṣṇa Caitanya Mahāprabhu, never He disclosed Himself that He is Kṛṣṇa Himself.
Although He was detected many times by His expert devotees like Sanātana Gosvāmī, Rūpa Gosvāmī, but He never said that, "I am Kṛṣṇa." He never said. Sometimes in Vṛndāvana some Vṛndāvana residents, they came to eulogize Him that, "Sir, You are Kṛṣṇa. We can understand." So He closed His ears like this, "Don't say like that. Oh, it is great offense to speak a common man as Kṛṣṇa." Yes.
So this is a teaching of Lord Caitanya, that to accept Kṛṣṇa as ordinary man is also offense, and similarly to accept an ordinary man as Kṛṣṇa, or God, that is also offense. He taught us that. That is going on nowadays. Any common man, he is declaring himself that, "I am God," and people are accepting. This is offense. We should understand who is actually Kṛṣṇa from the direction of the śāstra, not that any bogus man comes before us and declares himself that, "I am Kṛṣṇa and God," and we shall accept.
This is not good. But at the present moment there is no protection of the ruler. Everybody can go on like everything; there is no check. But this was not possible when there were kṣatriya kings in this country, in Bhārata-varṣa. Nobody could pretend as the Supreme Personality of Godhead. In Kṛṣṇa's time also, one king, he pretended himself that "I am Vāsudeva." So he was killed by Kṛṣṇa. So that is another story.
