18. To obviate invalid marriages when Eastern Catholics marry baptized Eastern non-Catholics and in order to promote fidelity in and the sanctity of marriage, as well as peace within the family, the Sacred Council determines that the canonical "form" for the celebration of these marriages is of obligation only for liceity; for their validity the presence of a sacred minister is sufficient, provided that other prescriptions of law are observed.(23)
18. Inabidi kuzuia ndoa batili wakati mkatoliki wa Mashariki anapofunga ndoa na asiye mkatoliki wa Mashariki aliyebatizwa; tena inapasa kushughulikia udumifu na utakatifu wa ndoa na pia amani katika nyumba; kwa sababu hiyo Mtaguso Mkuu unaamua kuwa utaratibu wa kisheria (formam canonicam) wa uadhimishaji ni wa lazima kwa habari ya uhalali (ad liceitatem) [wa ndoa]; na kwa habari ya uthabiti (ad validitatem) [wake] inatosha kuwepo kwa mhudumu (presentiam ministri sacri), hali vimefuatwa vipengere vingine vinavyodaiwa na sheria [za Kanisa][23].
