"Holy Scripture affirms that man and woman were created for one another: "It is not good that the man should be alone." The woman, "flesh of his flesh," his equal, his nearest in all things, is given to him by God as a "helpmate"; she thus represents God from whom comes our help. "Therefore a man leaves his father and his mother and cleaves to his wife, and they become one flesh." The Lord himself shows that this signifies an unbreakable union of their two lives by recalling what the plan of the Creator had been "in the beginning": "So they are no longer two, but one flesh."
~Catechism of the Catholic Church

Marriage is one of the seven sacraments of the Catholic Church. As such, the Catholic Church restricts sacramental marriage to those couples who meet certain requirements.

Regular Attendance at Mass:
The couple should be registered with the parish where they live and regularly attend Mass. Couples who are temporarily in the Lebanon area may need marriage preparation here and have the marriage at their "home parish" do not need to be registered but they should attend Mass regularly even if only one of them is Catholic.  Cohabitating couples should be regular in Mass attendance although they may not yet receive communion.

Couples are required to complete the FOCCUS Survey and attend at least 6 meetings with the priest or the person delegated to prepare couples for marriage.

Natural Family Planning:
Couples are required to attend a Natural Family Planning education series, which is usually a 3-part series.

Couples are required to attend a marriage preparation retreat. They may choose "Engaged Encounter" which is held in Portland periodically or they may choose a marriage preparation retreat at Mt. Angel. This retreat, "A Joy-filled Marriage," is on a periodic schedule. 

Baptismal Certificate:
Each person is to provide a copy of their baptismal certificate that is no more than 6 months old. It may be obtained from the parish of their baptism.

Freedom to Marry and Witness Forms:
Couples must complete the necessary form to establish Freedom to Marry with support of witnesses.

If either of the couple has been married previously, whether Catholic or not, an annulment process must be completed.
