This noun denotes acceptance or approval, especially the welcoming reception of something as worthy. Paul uses it in two pastoral epistles to emphasize the complete trustworthiness of core Christian teachings: 'the saying is trustworthy and worthy of all acceptance' regarding Christ saving sinners (1 Tim 1:15) and the promise of godliness (1 Tim 4:9). The classical range included receiving back what was one's own, entertaining guests, and gaining favor or approbation—but the New Testament narrows to the sense of accepting truth claims as deserving full endorsement.
