A solemn festival of the Jews, instituted in commemoration of their coming out of Egypt; because, the night before their departure, the destroying angel, who put to death the first-born of the Egyptians, passed over the houses of the Hebrews, without entering therein; because they were marked with the blood of the lamb, which was killed the evening before, and which for this reason was called the paschal lamb. See Exod. 12.
Charles Buck (1771-1815) was an English Independent minister, best known for the publication of his “Theological Dictionary”. According to the “Dictionary of National Biography”, a Particular Baptist minister named John C. Ryland (1723-1792) assisted Buck by writing many of the articles for the aforementioned publication. One may conclude, based not only Buck’s admiration for his friend Ryland, but also on the entries in his Theological Dictionary, that he stood head and shoulders with the High-Calvinists of his day.
