Modern Mennonites today allow any kind of wedding bands chosen by the couple, and permit ring ceremonies in wedding services, although some quietly put on the rings without a ceremony. Earlier, wedding rings were not permitted in many Mennonite groups, along with any kind of ring ceremony. Today many couples use engagement rings although some choose other lasting symbols to celebrate their commitment to marry each other. Most Mennonites believe in the principles of modesty and practicing good stewardship even in their wedding band choices, although that is open to individual interpretation and application. The most conservative Mennonite and Amish groups would still not permit wearing wedding bands.
