This article presented a metaphorical testimonial approach in the interpretation of 2 Timothy 2:19 and the use of sealing. As starting point, attention was given to the concept of ‘seal’ through the Old Testament and Ancient Near East. These periods attest the fact that sealing was also utilised in a figurative way as a sign of ownership, property and authenticity. Sfragís in 2 Timothy 2:19 describes the intimate relationship between Christ and his followers through the terms [foreign font omitted (personal and vital relationship that transcends in practice) and [foreign font omitted (mainly an exterior knowledge)]. These two vocables are in opposition to [foreign font omitted (to apostate from)]. The message expressed in 2:19 exemplifies the principles that Christ lived by and he empowered his followers to stand by. Sfragís in 2 Timothy 2:19 is an imitatio Christi response against the [foreign font omitted] of moral standards and entertainment in the ancient Roman world. It includes a rapid contemporary reflection on practical faithfulness for today’s life.
