The Birkat ha-Minim, (Hebrew ברכת המינים "Blessing on the heretics"), is a Jewish prayer of blessing on heretics in general, and sometimes Christians, though in this context "blessing" may also be a euphemism for a curse. The blessing is the 12th of the Eighteen Benedictions or Amidah.
The writing of the benediction is attributed to Shmuel ha-Katan at the supposed Council of Jamnia which was inserted in the "Eighteen Benedictions" as the 19th blessing in the silent prayer to be said thrice daily, the Amidah. The benediction is thus seen as related to the Pharisees, the Development of the Hebrew Bible canon, the split of early Christianity and Judaism as heresy in Judaism, the origins of Rabbinic Judaism, Origins of Christianity, Christianity in the 1st century, and history of early Christianity.
Textual variations 
"For the apostates let there be no hope. And let the arrogant government be speedily uprooted in our days. Let the noẓerim and the minim be destroyed in a moment. And let them be blotted out of the Book of Life and not be inscribed together with the righteous. Blessed art thou, O Lord, who humblest the arrogant" (Schechter)."
Identification of Minim 
The extent of the minim included by the birkat is debated. During the medieval period, whether the birkat had historically included Christians or not was the subject of disputations, a potential cause for persecution and thus a matter relevant for the safety of Jewish communities. It is generally viewed in modern studies that the term "heretics" at an early point in the split between Christianity and Judaism had included Jewish Christians. It was David Flusser's view (1992) that the Birkat haMinim was added in reference to the Sadducees.
Many scholars have seen reference to the Birkat haMinim in Justin Martyr's complaint to Trypho of the Jews "cursing in your synagogues those that believe on Christ." Reuven Kimelman (1981) challenged this, noting that Justin's description places the curse in the wrong sequence in the synagogue service.
