For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures
Although other lines from the Creed are based on the claims of scripture, both New Testament and Old, this line is a direct quotation. In this sense the line is unique in the Creed, as it quotes from New Testament scripture a confession grounded through Old Testament accordance.
But what does the phrase "and he rose again in accordance with the scriptures" actually mean?
One usual explanation is that the episodes conjoined with the phrase (i.e. Jesus' death, burial, resurrection) were the ones most demanding careful defense in the face of criticism from faithful Jews who claimed that their scriptures spoke otherwise. In the face of a scriptural legacy everywhere seen to be God's very word, the Church was faced with the challenge of what to do with Jesus. In this sort of climate, the Creed asserts that the stickiest moments in the life and ministry of Jesus were fully congruent with the Old Testament and its presentation of the Christ to come. Isaiah 53:5 - 12 had spoken of an expiatory death; Hosea 6:2 and Psalm 16:10 are likewise pressed into service as proof texts from the Old Testament, demonstrations that Jesus' death and raising were "in accordance with the scriptures".
Seitz doesn't dispute this way of understanding the character of scriptural accordance, but he does believe that it is exegetically too narrow and theologically too functional a view of the matter. The problem with the idea that the congruence between Jesus' resurrection and the plain sense of scripture is a matter of collecting scattered proof texts is that it fails to understand what is at stake in Paul's larger argument in 1 Corinthians 15, where the phrases appear.
