The Catechism of the Catholic Church #1601.
"The matrimonial covenant, by which a man and a woman establish between themselves a parthnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament".

MARRIAGE IN GOD'S PLAN.
CCC #1602.
Sacred Scripture begins with the creation of a man and woman in the image and likeness of God and concludes with a vision of "the wedding-feast of the Lamb".  Scripture speaks throughout of marriage and its "mystery," its institution and the meaning God has given it, its origin and its end, its various realizations throughtout  the history of salvation, the difficulties arising from sin and its renewal "in the Lord" in the New Covenant of Christ and the Church.

CCC #1603.
"The intimate community of life and love which constitutes the married state has been established by the Creator and endowed by him with its own proper laws...God himself is the author of marriage".  The vocation to marriage is written in the very nature of man and woman as they came from the hand of the Creator.  Marriage is not a purely human institution despite the many variations it may have undergone through the centuries in different cultures, social structures, and spiritual attitudes.  These differences should not cause us to forget its common and permanent characteristic.  Although the dignity of this institution is not transparent everywhere with the same clarity, some sense of the greatness of the matrimonial union exits in all cultures.  "The well-being of the individual person and of both human and Christian society is closely bound up with the healthy state of conjugal and family life".

Pope Francis' advice on Weddings:
"Make [your wedding] a real celebration.  Because marriage is a celebration - a Christian celebration, not a worldly feast!...
What happened in Cana 2,000 years ago, happend today at every wedding celebration: that which makes your wedding full and profoundly true will be the presence of the Lord who reveals himself and gives his grace.  It is his presence that offers the "good wine," he is the secret to full joy, that which truly warms the heart."



El Catecismo de la Iglesia Catolica #1601.
"La alianza matrimonial, por la que el varon y la mujer constituyen entre si un consorcio de toda vida, ordenado por su misma indole natural al bien de los conyuges y a la generacion y educacion de la prole, fue elevada por Cristo Nuestro Senor a la dignidad de sacramento entre bautizados".

EL MATRIMONIO EN EL PLAN DE DIOS.
CIC #1602.
La sagrada Escritura se abre con el relato de la creacion del hombre y de la mujer a imagen y semejanza de Dios (Gn 1: 26-27) y se cierra con la vision de las "bodas del Cordero" (Ap 19: 9; cf Ap 19: 7).  De un extremo a otro la Escritura habla del matrimonio y de su "misterio", de su institucion y del sentido que Dios le dio, de su origen y de su fin, de sus realizaciones diversas a lo largo de la historia de la salvacion, de sus dificultades nacidas del pecado y de su renovacion "en el Senor" (1Co 7: 39) todo ello en la perspectiva de la Nueva Alianza de Cristo y de la Iglesia (cf Ef 5: 31-32).

CIC #1603.
"La intima comunidad de vida y amor conyugal, esta fundada por el Creador y provista de leyes propias...El mismo Dios...es el autor del matrimonio". 
La vocacion al matrimonio se inscribe en la naturaleza misma del hombre y de la mujer, segun salieron de la mano del Creador.  El matrimonio no es una institucion puramente humana a pesar de las numerosas variaciones que ha podido sufrir a lo largo de los siglos en las diferentes culturas, estructuras sociales y actitudes espirituales.  Estas diversidades no deben hacer olvidar sus rasgos comunes y permanente.  A pesar de que la dignidad de esta institucion no se traluzca siempre con la misma claridad.  Existe en todas las culturas un cierto sentido de la grandeza de la union matrimonial.  "La salvacion de la persona y de la sociedad humana y cristiana estta estrechamente ligada a la prosperidad de la comunidad de la comunidad conyugal y familiar".


(El Santo Evangelio de Jesucristo segun San Mateo 19: 5-6)
"Por eso dejara el hombre a su padre y a su madre y se unira a su mujer, y los dos se haran una sola carne.  De manera que ya no son dos, sino una sola carne.  Pues bien, lo que Dios unio no lo separe el hombre."
