One is not coerced, but invited to a discovery of others, Christ and one's own self. This is the authentically Christian approach because it is the method of Christ Himself as we find Him in the Gospels. Households are not movements, but they can learn from these movements. In fact, there's probably nothing impossible about a household affiliating itself with a given movement in the Church. If Mrs. van Schaijik's facts and assertions are correct, the necessary change in households and the University's attitude toward them will come when greater freedom is given to those involved in households.
Freedom is the pre-requisite for love and friendship.
In addition, perhaps greater attention could be paid to discerning the motives and needs of students who wish to join households. I assume that the majority of households are not merely fraternities and sororities with a cross tacked-on. Joining with others in following Christ, even if the form of this following is transitory, is serious and should be approached in a serious way. Like any Catholic university, the household system should have as its goal preparing the total person for the challenges and pressures of the present age in service to the Church. To do so, both University and household system must serve the person, not rule over him or her.
