This is mostly due to the mass movement and transition of America compared to the fairly sedentary villages of Europe and the lack of priests in America. Marriage and divorce is also viewed much differently between cultures. In America divorces and remarrying is much more acceptable. European divorces occur at a much lower rate than America and remarriages are very uncommon unless one of the spouses has died. Family spirituality is much stronger in other Europe as well.
Religion belongs behind the four walls of the church in America.
Men are the spiritual leaders of the family in other Europe. Being religious is viewed as being weak in America. Promise Keepers has responded to this problem with putting the responsibility of spirituality on the man. Men have responded and given Promise Keepers a tremendous following. Anti clericalism is still very rampant in parts of Europe especially Ireland.
