Hi, Pnewton,
Would that things were that simple.
In 1968 the Canadian Bishops meeting in Winnipeg, issued their own direct challenge to the encyclical of Pope Paul VI condemnation of artificial birth control. Here is a link:
en.wikipedia.org/wiki/Winnipeg_Statement
Then we have this controversy with the Irish Bishops and their actions toward the sex abuse scandal in that country.
But, possibly more remarkable than these examples is the Great Schism - where hundreds of consecrated bishops have turned their back on Rome and gone their own way. The key to this entire matter on Catholic Dogma lies with Pope and the Magisterium - and not in a collection of Bishops. Again, there is nothing in this document from the US Bishops that declars or defines Catholic Dogma.
I do not want to sound dismissive because I really am not - but, somewhere along the line as we address just who is responsible for defining dogma - and how events like the Great Schism can take place if the Bishops are right (yet we have two camps that have condemned the teachings of the other) - we see that it is the entire Magisterium and the Pope who are responsible.
To my way of thinking we are to be charitable to all - and that means illegals, too!

We are to be just before we can be charitable - for justice holds the first place. I have seen no evidence that our laws are UNJUST - confusing, difficult, silly, loaded with inefficiencies and those are probably the good points!

But, which law are we going to pick apart and find such problems. US laws are intended primarily to protect US citizens and promote the common good. While no US law does either perfectly - they can be changed or abolished once enacted. Merely having individuals throw out laws they do not like is to invite chaos.
This may be a good topic for another thread - so, let me place this within the context of this particular thread. As Catholics we are required to listen to the teaching authority of the Church. We are required to listen to our Bishops. When it comes to illegal immigration I see two tacks have been developed: 1- The Bishops have effectively despaired of Mexico, Central and South America ever making their respective countries a place where their citizens want to stay and raise a family while building up their country and that leads to 2- The Bishops have singled out the US as now responsible for the health and welfare of those who flee their own country because we have ‘more’.
The US can not absorb the world. The US can work to help other countries to make improvements - but, it can not supply the political will in each repressive nation to come up with workable and successful economic systems that promote their own citizens.
God bless
Now, let’s take a look at what else the CCC teaches…
CCC 888

The teaching office
888 Bishops, with priests as co-workers, have as their first task “to preach the Gospel of God to all men,” in keeping with the Lord’s command.415 They are “heralds of faith, who draw new disciples to Christ; they are authentic teachers” of the apostolic faith "endowed with the authority of Christ."416
889 In order to preserve the Church in the purity of the faith handed on by the apostles, Christ who is the Truth willed to confer on her a share in his own infallibility. By a “supernatural sense of faith” the People of God, under the guidance of the Church’s living Magisterium, "unfailingly adheres to this faith."417
890 The mission of the Magisterium is linked to the definitive nature of the covenant established by God with his people in Christ. It is this Magisterium’s task to preserve God’s people from deviations and defections and to guarantee them the objective possibility of professing the true faith without error. Thus, the pastoral duty of the Magisterium is aimed at seeing to it that the People of God abides in the truth that liberates. To fulfill this service, Christ endowed the Church’s shepherds with the charism of infallibility in matters of faith and morals. The exercise of this charism takes several forms:
891 “The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful - who confirms his brethren in the faith he proclaims by a definitive act a doctrine pertaining to faith or morals. . . . The infallibility promised to the Church is also present in the body of bishops when, together with Peter’s successor, they exercise the supreme Magisterium,” above all in an Ecumenical Council.418 When the Church through its supreme Magisterium proposes a doctrine "for belief as being divinely revealed,"419 and as the teaching of Christ, the definitions "must be adhered to with the obedience of faith."420 This infallibility extends as far as the deposit of divine Revelation itself.421
892 Divine assistance is also given to the successors of the apostles, teaching in communion with the successor of Peter, and, in a particular way, to the bishop of Rome, pastor of the whole Church, when, without arriving at an infallible definition and without pronouncing in a “definitive manner,” they propose in the exercise of the ordinary Magisterium a teaching that leads to better understanding of Revelation in matters of faith and morals. To this ordinary teaching the faithful "are to adhere to it with religious assent"422 which, though distinct from the assent of faith, is nonetheless an extension of it.**
