Canon 277. §1 Clerics are obliged to observe perfect and perpetual continence for the sake of the Kingdom of heaven, and are therefore bound to celibacy. Celibacy is a special gift of God by which sacred ministers can more easily remain close to Christ with an undivided heart, and can dedicate themselves more freely to the service of God and their neighbour.

§2 Clerics are to behave with due prudence in relation to persons whose company can be a danger to their obligation of preserving continence or can lead to scandal of the faithful.

§3 The diocesan Bishop has authority to establish more detailed rules concerning this matter, and to pass judgement on the observance of the obligation in particular cases.

§1. Clerici obligatione tenentur servandi perfectam perpetuamque propter Regnum coelorum continentiam, ideoque ad coelibatum adstringuntur, quod est peculiare Dei donum, quo quidem sacri ministri indiviso corde Christo facilius adhaerere possunt atque Dei hominumque servitio liberius sese dedicare valent.

§2. Debita cum prudentia clerici se gerant cum personis, quarum frequentatio ipsorum obligationem ad continentiam servandam in discrimen vocare aut in fidelium scandalum vertere possit.

§3. Competit Episcopo dioecesano ut hac de re normas statuat magis determinatas utque de huius obligationis observantia in casibus particularibus iudicium ferat.

Canon 285. §1 Clerics are to shun completely everything that is unbecoming to their state, in accordance with the provisions of particular law.

§2 Clerics are to avoid whatever is foreign to their state, even when it is not unseemly.

§3 Clerics are forbidden to assume public office whenever it means sharing in the exercise of civil power.

§4 Without the permission of their Ordinary, they may not undertake the administration of goods belonging to lay people, or secular offices which involve the obligation to render an account. They are forbidden to act as surety, even concerning their own goods, without consulting their proper Ordinary. They are not to sign promissory notes which involve the payment of money but do not state the reasons for the payment.

§1. Clerici ab iis omnibus, quae statum suum dedecent, prorsus abstineant, iuxta iuris particularis praescripta.

§2. Ea quae, licet non indecora, a clericali tamen statu aliena sunt, clerici vitent.

§3. Officia publica, quae participationem in exercitio civilis potestatis secumferunt, clerici asssumere vetantur.

§4. Sine licentia sui Ordinarii, ne ineant gestiones bonorum ad laicos pertinentium aut officia saecularia, quae secumferunt onus reddendarum rationum; a fideiubendo, etiam de bonis propriis, inconsulto proprio Ordinario, prohibentur; item a subscribendis syngraphis, quibus nempe obligatio solvendae pecuniae, nulla definita causa, suscipitur, abstineant.

Canon 286. Clerics are forbidden to practise commerce or trade, either personally or through another, for their own or another’s benefit, except with the permission of the lawful ecclesiastical authority.

Prohibentur clerici per se vel per alios, sive in propriam sive in aliorum utilitatem, negotiationem aut mercaturam exercere, nisi de licentia legitimae auctoritatis ecclesiasticae.
