CCC 1658 We must also remember the great number of single persons who, because of the particular circumstances in which they have to live - often not of their choosing - are especially close to Jesus' heart and therefore deserve the special affection and active solicitude of the Church, especially of pastors. Many remain without a human family often due to conditions of poverty. Some live their situation in the spirit of the Beatitudes, serving God and neighbour in exemplary fashion. The doors of homes, the "domestic churches," and of the great family which is the Church must be open to all of them. "No one is without a family in this world: the Church is a home and family for everyone, especially those who 'labour and are heavy laden.'"
Virginity for the sake of the Kingdom
CCC
1618 Christ is the center of all Christian life. The bond with him takes precedence over all other bonds, familial or social.113 From the very beginning of the Church there have been men and women who have renounced the great good of marriage to follow the Lamb wherever he goes, to be intent on the things of the Lord, to seek to please him, and to go out to meet the Bridegroom who is coming.114 Christ himself has invited certain persons to follow him in this way of life, of which he remains the model:
"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."115
1619 Virginity for the sake of the kingdom of heaven is an unfolding of baptismal grace, a powerful sign of the supremacy of the bond with Christ and of the ardent expectation of his return, a sign which also recalls that marriage is a reality of this present age which is passing away.116
1620 Both the sacrament of Matrimony and virginity for the Kingdom of God come from the Lord himself. It is he who gives them meaning and grants them the grace which is indispensable for living them out in conformity with his will.117 Esteem of virginity for the sake of the kingdom118 and the Christian understanding of marriage are inseparable, and they reinforce each other:
Whoever denigrates marriage also diminishes the glory of virginity. Whoever praises it makes virginity more admirable and resplendent. What appears good only in comparison with evil would not be truly good. The most excellent good is something even better than what is admitted to be good.119
TEACHING AS A VOCATION ...
Beautiful indeed and of great importance is the vocation of all those who aid parents in fulfilling their duties and who, as representatives of the human community, undertake the task of education in schools. This vocation demands special qualities of mind and heart, very careful preparation, and continuing readiness to renew and to adapt.

The laity build up the Kingdom of God in a way that priests and religious cannot. See
Lumen Gentium 31:
But the laity, by their very vocation, seek the kingdom of God by engaging in temporal affairs and by ordering them according to the plan of God. They live in the world, that is, in each and in all of the secular professions and occupations. They live in the ordinary circumstances of family and social life, from which the very web of their existence is woven. They are called there by God that by exercising their proper function and led by the spirit of the Gospel they may work for the sanctification of the world from within as a leaven. In this way they may make Christ known to others, especially by the testimony of a life resplendent in faith, hope and charity. Therefore, since they are tightly bound up in all types of temporal affairs it is their special task to order and to throw light upon these affairs in such a way that they may come into being and then continually increase according to Christ to the praise of the Creator and the Redeemer.
Full-time lay apostleship is envisaged by the Church:Ministers of lesser rank are also sharers in the mission and grace of the Supreme Priest. In the first place among these ministers are deacons, who, in as much as they are dispensers of Christ's mysteries and servants of the Church, should keep themselves free from every vice and stand before men as personifications of goodness and friends of God.(225)
Clerics, who are called by the Lord and are set aside as His portion in order to prepare themselves for the various ministerial offices under the watchful eye of spiritual shepherds, are bound to bring their hearts and minds into accord with this special election (which is theirs). They will accomplish this by their constancy in prayer, by their burning love, and by their unremitting recollection of whatever is true, just and of good repute. They will accomplish all this for the glory and honor of God.
Besides these already named, there are also laymen, chosen of God and called by the bishop. These laymen spend themselves completely in apostolic labors, working the Lord's field with much success.
(LG 41)
St Paul in 1 Corinthians spells out clearly that it is for each Christian to discern whether he can cope with the celibacy for the sake of the Kingdom, a condition that he recommends ...
Brothers, everyone should continue before God in the state in which he was called.
25
Now in regard to virgins, I have no commandment from the Lord,
11 but I give my opinion as one who by the Lord's mercy is trustworthy.
26
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.
27
Are you bound to a wife? Do not seek a separation. Are you free of a wife? Then do not look for a wife.
28
If you marry, however, you do not sin, nor does an unmarried woman sin if she marries; but such people will experience affliction in their earthly life, and I would like to spare you that.
29
I tell you, brothers, the time is running out. From now on, let those having wives act as not having them,
30
those weeping as not weeping, those rejoicing as not rejoicing, those buying as not owning,
31
those using the world as not using it fully. For the world in its present form is passing away.
32
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.
33
But a married man is anxious about the things of the world, how he may please his wife,
34
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.
35
I am telling you this for your own benefit, not to impose a restraint upon you, but for the sake of propriety and adherence to the Lord without distraction.
36
If anyone thinks he is behaving improperly toward his virgin, and if a critical moment has come and so it has to be, let him do as he wishes. He is committing no sin; let them get married.
37
The one who stands firm in his resolve, however, who is not under compulsion but has power over his own will, and has made up his mind to keep his virgin, will be doing well.
38
So then, the one who marries his virgin does well; the one who does not marry her will do better.
