[628] For the seal in baptism, cf. Clem. Al. Strom. 2. 3; Quis dives, 42, ap. Euseb. Hist. 3. 23; Euseb. Vita Const. 1. 4. 62; Cyr. Hier. Catech. 5; Greg. Naz. Orat. 40, p. 639; Orig. c. Cels. 6. 27. For the use of imagery and the terms relating to sealing—illumination—initiation—from the mysteries, Clem. Al. Protrep. 12. The effect of baptism is illumination, perfection, Pædag. 1. 6; hence sins before and after baptism, i.e. enlightenment, are different, Strom. 2. 13. Early instances of σφραγὶς are collected in Gebhardt on 2 Clem. pp. 168, 169; cf. also Cyr. Hier. Catech. 18. 33, p. 301.

[636] Sozomen, i. 3. 5; ii. 7. 8; iv. 20. 3; vi. 38. 15; vii 8. 7, et passim. These examples do not by any means exhaust or even adequately represent the obligations in the sphere of language, and of the ideas it at once denotes and connotes, which the ecclesiastical theory and practice of baptism lies under to the mysteries; but they may help to indicate the degree and nature of the obligation.
