“Holy Scripture gives us no specific prescriptions with regard to burial. We have an example in the tender way Jesus was buried by his disciples; the same is true of Stephen (Acts 8:2).
We are allowed to mourn and to be sad as appears from both the Old Testament (Gen. 23:2; 37:34-35; 50:1-3; 1 Sam. 25:1) and the New Testament (Luke 7:12-13). Jesus himself (John 11:33-35), Mary (John 20:11), and the disciples (Mark 16:10; Luke 24:17; John 16:20) mourned, and the church at Ephesus mourned for Paul (Acts 20:37).
Death is an evil. Yet Christian mourning is different from pagan mourning. No sorrowing without hope (1 Thess. 4:13), no worldly sorrow (2 Cor. 7:10).
The Christians changed a funeral into a feast of celebration and triumph.
They buried their dead not at night but during daytime, in the full light of day, dressed in white robes, accompanied by retinues and spectators, without wailing women, without wreaths on the body or the coffin.”
