The question of who may receive communion likewise varies. In historic Anglican practice, the altar was "fenced" from those whose manner of living was considered to be unrepentantly sinful. As parishes grew and the private lives of individuals became less accessible to public knowledge, this practice receded — although priests will, on occasion, refuse to admit to communion those whom they know to be actively engaged in notoriously sinful behaviour, such as criminal activity. Most Anglican provinces keep an "open table", meaning that all baptised Christians are welcome to receive communion. In many others, access to the sacrament is reserved for those who have been both baptised and confirmed, either in the Anglican or another tradition. Those who are ineligible or do not wish to receive are frequently encouraged to come forward and cross their arms to form a sign of the cross to indicate that they wish to receive a blessing.
