According to the Catholic Church, a "Saint" is anyone in heaven, whether recognized on Earth or not, who form the "great cloud of witnesses" (Hebrews 12:1). These "may include our own mothers, grandmothers or other loved ones (cf. 2 Tim 1:5)" who may have not always lived perfect lives but "amid their faults and failings they kept moving forward and proved pleasing to the Lord". "The patriarchs, prophets, and certain other Old Testament figures have been and always will be honored as saints in all the church's liturgical traditions." Sometimes the word "saint" also denotes living Christians. The Catholic Church teaches that it does not "make" or "create" saints, but rather recognizes them.
