An unmarried man is concerned about the Lord's affairs—how he can please the Lord. But a married man is concerned about the affairs of this world—how he can please his wife— and his interests are divided.
The disciples said to him, "If that is the case of a man with his wife, it is not expedient to marry." But he said to them, "Not all men can receive this precept, but only those to whom it is given. For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. He who is able to receive this, let him receive it." - Matt 19:10-12
And Jesus said to them, "The sons of this age marry and are given in marriage; but those who are accounted worthy to attain to that age and to the resurrection from the dead neither marry nor are given in marriage, for they cannot die any more, because they are equal to angels and are sons of God, being sons of the resurrection. - Luke 20:34-36
in 1 Corinthians 7, in that very chapter Paul actually endorses celibacy for those capable of it: "To the unmarried and the widows I say that it is well for them to remain single as I am. But if they cannot exercise self-control, they should marry. For it is better to marry than to be aflame with passion" (7:8-9).
1 Cor 7:6-7
This I say by way of concession, however, not as a command. Indeed, I wish everyone to be as I am (single? widowed?), but each has a particular gift from God, one of one kind and one of another.
1 Cor 7:25-26
Now in regard to virgins, I have no commandment from the Lord, but I give my opinion as one who by the Lord's mercy is trustworthy. So this is what I think best because of the present distress: that it is a good thing for a person to remain as he is.
1 Cor 7:32-34
I should like you to be free of anxieties. An unmarried man is anxious about the things of the Lord, how he may please the Lord. But a married man is anxious about the things of the world, how he may please his wife, and he is divided. An unmarried woman or a virgin is anxious about the things of the Lord, so that she may be holy in both body and spirit. A married woman, on the other hand, is anxious about the things of the world, how she may please her husband.
Moreover Jesus Christ was a great priest who was never married but he considered Church as his bride.
