The Srimad-Bhagavatam states that any bona fide preacher of God consciousness must have the qualities of titiksa (tolerance) and karuna (compassion). In the character of Lord Jesus Christ we find both these qualities.

To kill nothing, that is love.

A grain of devotion is more valuable thank tons of faithlessness.

A bona fide spiritual master, under the guidance of authorities, can turn anyone to the Vaisnava cult so that naturally he may come to the topmost position of a brahmana.

One who loves Krishna will give Him whatever He wants, and he avoids offering anything which is undesirable or unasked for. Thus, meat, fish and eggs should not be offered to Krishna...Vegetables, grains, fruits, milk and water are the proper foods for human beings and are prescribed by Lord Krishna Himself. Whatever else you eat, can not be offered to Him, since He will not accept it.

A devotee should be fixed in the conclusion that, the spiritual master cannot be subject to criticism and should never be considered equal to a common man.

A spiritual master who is one hundred percent Krishna conscious is the bona fide spiritual master.
