About the same date (c. 400) Rufinus (Migne, P.L., XXI, 337) gives a detailed account of the composition of the Creed, which account he professes to have received from earlier ages (tradunt majores nostri). Although he does not explicitly assign each article to the authorship of a separate Apostle, he states that it was the joint work of all, and implies that the deliberation took place on the day of Pentecost. Moreover, he declares that "they for many just reasons decided that this rule of faith should be called the Symbol", which Greek word he explains to mean both indicium, i.e. a token or password by which Christians might recognize each other, and collatio, that is to say an offering made up of separate contributions. A few years before this (c. 390), the letter addressed to Pope Siricius by the Council of Milan (Migne, P.L., XVI, 1213) supplies the earliest known instance of the combination Symbolum Apostolorum ("Creed of the Apostles") in these striking words: "If you credit not the teachings of the priests . . . let credit at least be given to the Symbol of the Apostles which the Roman Church always preserves and maintains inviolate." The word Symbolum in this sense, standing alone, meets us first about the middle of the third century in the correspondence of St. Cyprian and St. Firmilia, the latter in particular speaking of the Creed as the "Symbol of the Trinity", and recognizing it as an integral part of the rite of baptism (Migne, P.L., III, 1165, 1143). It should be added, moreover, that Kattenbusch (II, p. 80, note) believes that the same use of the words can be traced as far back as Tertullian. Still, in the first two centuries after Christ, though we often find mention of the Creed under other designations (e.g. regula fidei, doctrina, traditio), the name symbolum does not occur.
from Newadvent.org
The Catholic ideal is the complete person, with a cool head and a warm heart, a hard head and a soft heart. The mere intellectual has a cool heart; the anti-intellectual has a hot head. The intellectual has a hard heart, the anti-intellectual has a soft head. The Church puts the severed parts in the right order because the Church has the blueprint: Christ (Eph 4:13). The Church has always had a conservative head and a liberal heart, and the world has never understood her, just as it never understood Christ.
