Firm in one's opinion

Confident in his opinion. Determined and stubborn regarding his position.

(“According to the decision on the matter, to stand firm in his opinion not to permit the circumcision for the son of a non-Jewish woman, until everyone knows that a son born to a non-Jewish woman is a complete foreigner, and one who marries a non-Jewish woman begets foreign children, and the only solution for the children is that if they grow up, they must convert” – Responsa Sridei Esh, Part 1, Siman 46, page 128)
