As it is stated, White, black, and purple are options. Black I can understand, but I can also understand the critics that one does not want to “mourn as those with no hope”, but black also says it is OK to mourn. Someone has left us. It is sad.
White I can honestly say I cannot understand. When I am told that it is to celebrate the resurrection and the new life of the deceased. This defeats the liturgical and theological reasoning for a funeral Mass: To pray for the soul. To pray that this person’s sins may be forgiven. We are not there to celebrate someone’s life on earth. The color white, being the color of saints, seems to give the impression of canonization or surety that someone is in the kingdom of heaven; something we are not sure of. Certainly individuals can think so, but in the gathering of the Church for prayer, it is not proper to allude to such things.
I really feel the most proper color for funerals is purple; the color of prayer and penitence. We gather together to pray and do penance for the deceased. What would be more proper that to wear the color of penitence?
Of course, this is just my two cents and the decision on what is allowed and not allowed is above my pay grade.
