Attending Mass each Sunday is a serious obligation and great privilege for Catholics. Talk honestly about how this will work in your marriage, especially if the non-Catholic spouse also attends a different service.
Couples are strongly encouraged to find ways to pray together — even something as simple as grace before meals, the Lord’s Prayer, spontaneous prayers of thanksgiving for blessings received, or a shared moment of silent prayer. These habits create unity without forcing uniformity.The Catholic spouse must make a solemn promise before God and the Church to do all in their power to raise children in the Catholic faith. This is not optional. Couples should discuss how Baptism, First Communion, Confirmation, and Catholic formation will be handled. While the non-Catholic spouse does not need to make the same promise, they must agree not to obstruct the Catholic spouse in fulfilling it.
The religious education of children in the Catholic faith can be a particularly difficult issue. Both the husband and wife are bound by this parental responsibility and must not ignore it or any of its connected obligations. However, the non-Catholic spouse can alleviate some difficulties by showing support and participating in the educational efforts in ways their conscience allows.
