Here is a bit of the interview (slightly less out of context)
Aren’t there two types of dogmas? Aren’t there unmovable dogmas that were instituted by Jesus and then there are those that came afterwards, during the course of the church’s history, created by men and therefore susceptible to change?
Certainly. There are dogmas that are defined and untouchable.
Celibacy is not –
It is not a church dogma and it can be discussed because it is a church tradition.
That goes back to what period?
To the early centuries. After its implementation, it was applied during the first millennium and after the Council of Trent, the church enforced it. It is a tradition, and the concept lives on within the church because during the course of all these years things have happened that have contributed to develop God’s revelation. This was completed with the death of the last apostle, Saint John. What happened afterwards was an increase in the comprehension and the living out of the revelation.
Speaking of celibacy –
The work the church did to institute ecclesiastical celibacy must be considered. We cannot simply say that it is part of the past. It is a great challenge for the pope, because he is the one with the ministry of unity and all of those decisions must be made thinking of the unity of the church and not to divide it. Therefore we can talk, reflect, and deepen on these subjects that are not definite, and we can think of some modifications, but always with consideration of unity, and all according to the will of God. It is not about what I would like but what God wants for His church.
What does he want?
God speaks in many ways. We must be careful to this voice that guides us on the causes and solutions. We have to take into account, at the moment of taking a decision, these criteria as well as to the opening to the spirit of the times.
Hope this helps.
