"Mortuary contexts also provide some of the earliest evidence for a Christian visual culture. From the first part of the third century, Christian catacombs featured art depicting biblical scenes of resurrection, salvation, and redemption (Lazarus, Susanna, Daniel in the lions' den, the sacrifice of Isaac), alongside both Christian symbols and pagan images that could convey new meanings (Bisconti, Chapter 11; cf. Bisconti 1999, 100-30 for an overview of common themes). Scholars have likewise long recognized the link between earliest Christian sculpture and themes present in funerary contexts (Kristensen, Chapter 18; Jensen 2000). Parani (Chapter 17) discusses how the earliest lamp forms of the third century with scenes of Noah, Jonah, and the Good Shepherd paralleled funerary art in other media and evoked the Christian concept of redemption and resurrection. Perhaps these mortuary contexts account for the appearance of Christian imagery in other media, although the emergence of amulets with Christian imagery as early as the third or even second centuries seems to indicate a somewhat different purpose; harnessing the power of the Christian god in their daily affairs (Cline, Chapter 19). Despite the troubling absence of secure archaeological contexts, the evidence does point to distinct forms of Christian material culture emerging by the third century that often point to the theological reflection on Christ's victory over death."
