Africa (Alexandria) Origen
"After the festival of the unceasing sacrifice (the crucifixion) is put the second festival of the Sabbath, and it is fitting for whoever is righteous among the saints to keep also the festival of the Sabbath. There remaineth therefore a sabbatismus, that is, a keeping of the Sabbath, to the people of God (Hebrews 4:9)." "Homily on Numbers 23," par.4, in Migne, "Patrologia Graeca," Vol. 12,cols. 749, 750.
