The 1969 revision of the Roman Rite inserted into the Mass the solemn ceremony of blessing ashes and placing them on heads, but also explicitly envisaged a similar solemn ceremony outside of Mass. The Book of Blessings contains a simple rite. While the solemn rite would normally be carried out within a church building, the simple rite could appropriately be used almost anywhere. While only a priest or deacon may bless the ashes, laypeople may do the placing of the ashes on a person's head. Even in the solemn rite, lay men or women may assist the priest in distributing the ashes. In addition, laypeople take blessed ashes left over after the collective ceremony and place them on the head of the sick or of others who are unable to attend the blessing. (In 2014, Anglican Liverpool Cathedral likewise offered to impose ashes within the church without a solemn ceremony.)
