Episcopalian and Protestant have a variety of wedding ceremony vows; it all depends on a specific denomination. Here are some examples of traditional vows:
Episcopalian
"In the name of God, I, __________, take you, ________, to be my husband/wife, to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness, in health, to love and to cherish, until we are parted by death. This is my solemn vow."
Protestant
The minister says: "Will you have this woman to be your wedded wife, to live together in holy matrimony? Will you love her, comfort her, honor and keep her in sickness and in health, in sorrow and in joy, and forsaking all others, be faithful to her as long as you both shall live?"
The groom answers: "I do."
The vows are then repeated for the bride.
Or, the minister makes this statement: "This celebration is an outward token of a sacred and inward union of the hearts which the Church does bless and the State makes legal -- a union created by loving purpose and kept by abiding will."
The minister then asks the bride and groom: "Is it in this spirit and for this purpose that you have come here to be joined together?"
The bride and groom reply: "Yes, I have."
Then the bride and groom individually say these vows: "I take you to be my wedded wife/husband, to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, 'til death do us part. This is my solemn vow. According to God's holy ordinance; and thereto I plight you my troth."
