BG 2.8, Purport:

Lord Caitanya said that one who is master in the science of Kṛṣṇa consciousness, regardless of his social position, is the real spiritual master.

kibā vipra, kibā nyāsī, śūdra kene naya

yei kṛṣṇa-tattva-vettā, sei 'guru' haya

"It does not matter whether a person is a vipra (learned scholar in Vedic wisdom) or is born in a lower family, or is in the renounced order of life-if he is master in the science of Kṛṣṇa, he is the perfect and bona fide spiritual master." (Caitanya-caritāmṛta, Madhya 8.128) So without being a master in the science of Kṛṣṇa consciousness, no one is a bona fide spiritual master.

SB Canto 1

SB 1.7.43, Purport:

According to revealed scriptures, a teacher or spiritual master is liable to be rejected if he proves himself unworthy of the position of a guru or spiritual master. A guru is called also an ācārya, or a person who has personally assimilated all the essence of śāstras and has helped his disciples to adopt the ways.
