2 Corinthians 11:12 - 15
KJV - 12 But what I do, that I will do, that I may cut off occasion from them which desire occasion; that wherein they glory, they may be found even as we. 13 For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.

A "false apostle", for Paul in the verse above, plus still in our day, and until Jesus returns, is anyone and everyone who would share "another Gospel" than that of Jesus, The King with someone who asks a Christian about our "hope" (1 Peter 3:15-17)!
