1 Corinthians 11:11
11 Nevertheless neither is the
man without the woman, neither the
woman without the man, in the Lord.
Man and woman were created to be together and when they are joined together they become one flesh. This is a union that can be eternal in nature.
Matthew 19:5-6
5 And said, For this cause shall a man leave father and mother, and shall
cleave to his wife: and they twain shall be one flesh?
6 Wherefore they are no more twain, but one flesh. What therefore God hath
joined together, let not man
put asunder.
In this union, God has given man the power to be more like God. The power of procreation should be held sacred and only used within the prescribed use that God has given man. Devils do not have this power but God has the power to procreate children. Only those who learn to honor this gift from God will have this power in the eternities. Acts that denigrate this wonderful power given to us by God are adultery, fornication, homosexuality, bestiality, etc.
The Catholic church's teachings on celibacy are not a life long teaching in Christ. Such teachings are for missionaries in the field. It is the purpose of man to leave his father and mother and be joined with his wife.
Mark 10:6-8
6 But from the beginning of the creation God made them male and female.
7 For this cause shall a
man leave his father and mother, and cleave to his
wife;
8 And they twain shall be one flesh: so then they are no more twain, but one flesh.
