The alternative vel integri vel casti is here disjunctive. It means that married men were also eligible for the diaconate if they renounced the conjugal relations.
The interdict of the Lusitatnian bishops mentioned in the canon probably refers to some provincial council in Lusitania. Its date is difficult to establish. S. Heid thought that it probably adopted the requirement of clerical celibacy from the so-called Directa decretal issued by Pope Siricius in 385 (in form of the letter to Bishop Himerius of Tarragona, ). Therefore it would have taken place between 385 and 400 (Heid 2000: 224). J. Suberbiola Martinez (1987: 87-104) proposed that the Lusitanian council took place in 396 and its canons were preserved in the collections of canons of the Council of Elvira (canon 23 to 36). The interdict issued by Lusitanian bishops would be then the same text we know today as canon 33 of the Council of Elvira . For the criticism of this theory see Weckwerth 2004: 102-103, n. 12.
