"When the Feast was already half over, Jesus went up into the temple [court] and began to teach.
15 The Jews were astonished. They said, How is it that this Man has learning [is so versed in the sacred Scriptures and in theology] when He has never studied?
16 Jesus answered them by saying, My teaching is not My own, but His Who sent Me.
17 If any man desires to do His will (God’s pleasure), he will know (have the needed illumination to recognize, and can tell for himself) whether the teaching(I share) is from God or whether I am speaking from Myself and of My own accord and on My own authority.
18 He who speaks on his own authority seeks to win honor for himself. [He whose teaching originates with himself seeks his own glory.] But He Who seeks the glory and is eager for the honor of Him Who sent Him, He is true; and there is no unrighteousness or falsehood or deception in Him."
(John 7:14-18)
If you want to discern whether anybody who shares the gospel of Jesus Christ Crucified is *genuine* check whether he/she is trying to praise himself/herself or draw people to himself/herself or attract people to his/her own denomination or open his/her own church/fellowship
OR
He/she wants to lead himself/herself and those who listen or encounter his/her teachings to *FOLLOW JESUS CHRIST CRUCIFIED ONLY AS THE SON OF GOD AND THE ONLY MEANS OF HUMAN SALVATION*

BY THEIR FRUITS YOU SHALL KNOW THEM.

What about baby Christians who are just trying to find their feet?

How are they supposed to discern and not be deceived?

@ochibuogwu5 there are churches that preach the crucifixion of Jesus as a smokescreen for the sinister evil they perpetrate in the secret...your criteria is flawed and can be penetrated by satan. Besides Paul declares that we are to go beyond your criteria which is basically part of the first principles of the oracles of God to handle more bizarre revelations...you cannot tell a true church unless you are in the spirit because the Spirit bears witness with our spirit!

Go into your house, pray, worship and wait upon the LORD Jesus for dreams and revelations...soon enough your supernatural senses will lighten up as the Holy Ghost works through you. As soon as you come in contact with satanic doctrine your heart will detect it and reject it...the Holy Ghost is the master key to all mysteries and you can only be filled with Him by continuous fellowship and communion with Him.
