Gospel of John (15) Jesus and the Jews

 If I had not come, and spoken to them, they would not have sin; but now they have no excuse for their sin.  He that hateth me, hateth my Father also.  If I had not done among them the works that no other man hath done, they would not have sin; but now they have both seen and hated both me and my Father.   But that the word may be fulfilled which is written in their law: They hated me without cause

Cornelius A Lapide:

Ver. 22.—If I had not come and spoken, &c., they would not have sin, &c. Sin, viz. of unbelief and hatred, in that they calumniate, and are hostile to, My doctrine and life. Observe: the Scribes and Pharisees before Christ came had true faith, not only in God, but also in Christ as about to come. But when He did come they would not acknowledge Him, because they saw Him poor and lowly, and because He reproved their vices. Wherefore they then became unbelievers, and lost the faith by their own obstinacy. For Jesus abundantly proved to them that He was the Christ, wherefore they were without excuse because they believed Him not. 

Ver. 23.—He that hateth Me hateth My Father also, because I am come as sent by the Father, and I have spoken the things which He wished Me to speak. Wherefore by despising and hating Me, they despise and hate God the Father. As he who despiseth an ambassador despises the king who sends him. 

Ver. 25.—But that the word may be fulfilled which is written in their law (i.e., in the Old Test., viz. Ps. lix. 5, and xxv. 29), they hated Me gratis (Vulg.), i.e. without a cause, without My fault, and therefore wickedly and unjustly. For I have given them no other cause of hate, but supremest love. Observe the word that does not signify the end intended, but denotes that which happened as a matter of fact from the unbelief and obstinacy of the Jews. The meaning is, And thus there followed that which David and Isaias foretold would be, viz. that the Jews would without a cause pursue Christ with hate.
