Raider Fan could support the excerpted passages from this old Council but he also knows they would sound hateful and arrogant to the vast majority of Catholics today.
Imagine a teaching of today that, rightfully, spoke of Jews as infidels; imagine a Council of today condemning the growing popularity of Seders; or, even more implausible, imagine the Church educating evangelists with the express intent of converting Jews?
Poor Pope Francis would be apoplectic..
It would never happen, but Raider Fan can dream...
Session 19 - 7 September 1434
The holy general synod of Basel, legitimately assembled in the holy Spirit representing the universal church, for an everlasting record. As a dutiful mother is ever anxious about the health of her children and is uneasy until any dissension among them has been quietened, so and to a much greater extent holy mother church, which regenerates its children to eternal life, is wont to strive with every effort that all who go by the name of Christian may put aside all quarrelling and may guard in fraternal charity the unity of the faith, without which there can be no salvation.
I... Although many from the beginning thought that the Bohemian affair was not only difficult but almost impossible and judged our labours to be a waste of time and useless, nevertheless our lord Jesus Christ, to whom nothing is impossible, has so safely directed the business until now that the invitation to the Bohemians has been of much greater benefit to holy church than the many powerful armies which frequently invaded their country.
... Moreover, we trust that with God's help another benefit will accrue to the Christian commonwealth; because from this union, once it is established, there is hope that very many from the abominable sect of Mahomet will be converted to the catholic faith. What, then, should not be attempted and done by Christ's faithful for so holy and salutary an objective? What Catholic is not in duty bound to risk not only the passing substance of this world but even his body and soul for such an advance of the Christian name and the orthodox faith?

[Decree on Jews and neophytes]
The holy general synod of Basel, legitimately assembled in the holy Spirit, representing the universal church, for an everlasting record. This holy synod following in the footsteps of our saviour Jesus Christ, desires in deepest charity that all may acknowledge the truth of the gospel and thereafter abide in it faithfully. By these salutary instructions it desires to provide measures whereby Jews and other infidels may be converted to the orthodox faith and converts may remain steadfastly in it. It therefore decrees that all diocesan bishops should depute persons well trained in scripture, several times a year, in the places where Jews and other infidels live, to preach and expound the truth of the catholic faith in such a way that the infidels who hear it can recognise their errors. They should compel infidels of both sexes who have reached the age of discretion, to attend these sermons under pain both of being excluded from business dealings with the faithful and of other apposite penalties. But the bishops and the preachers should behave towards them with such charity as to gain them for Christ not only by the manifestation of the truth but also by other kindnesses. The synod decrees that Christians of whatever rank or status who in any way impede the attendance of Jews at these sermons, or who forbid it, automatically incur the stigma of being supporters of unbelief.
Since this preaching will be more fruitful in proportion to the linguistic skill of the preachers, we decree that there must be faithful observance of the constitution of the council of Vienne, which ordered the provision in certain universities of teachers of the Hebrew, Arabic, Greek and Chaldean languages. So that this may be more adhered to, we wish that the rectors of these universities should add to what they swear to on taking office, that they will endeavour to observe the said constitution. It should be clearly laid down, at the councils of the provinces in which these universities are situated, that the teachers of the said languages are to be adequately recompensed.
Furthermore, renewing the sacred canons, we command both diocesan bishops and secular powers to prohibit in every way Jews and other infidels from having Christians, male or female, in their households and service, or as nurses of their children; and Christians from joining with them in festivities, marriages, banquets or baths, or in much conversation, and from taking them as doctors or agents of marriages or officially appointed mediators of other contracts. They should not be given other public offices, or admitted to any academic degrees, or allowed to have on lease lands or other ecclesiastical rents. They are to be forbidden to buy ecclesiastical books, chalices, crosses and other ornaments of churches under pain of the loss of the object, or to accept them in pledge under pain of the loss of the money that they lent. They are to be compelled, under severe penalties, to wear some garment whereby they can be clearly distinguished from Christians. In order to prevent too much intercourse, they should be made to dwell in areas, in the cities and towns, which are apart from the dwellings of Christians and as far distant as possible from churches. On Sundays and other solemn festivals they should not dare to have their shops open or to work in public.
[About those who desire conversion to the faith]
If any of them wishes to be converted to the catholic faith, all his goods, both movable and immovable, shall remain intact and unharmed in his possession. But if his goods were acquired by usury or illicit dealings, and the persons to whom restitution ought to be made are known, it is absolutely necessary that this restitution be made, since the sin is not forgiven unless the illegal object is restored. However, if these persons are no longer an issue because the church has turned the goods to pious uses, this holy synod, acting for the universal church, grants in favour of the baptism received that the goods should remain with the church as a pious use, and it forbids both ecclesiastics and secular persons, under pain of divine anathema, to cause or allow to be caused any vexation on this count under any pretext whatsoever, but they should regard it as a great gain to have won such persons for Christ. Moreover since, as it is written, if anyone has this world's goods and sees his brother in need, yet closes his heart against him, how does God's love abide in him ?, this holy synod through the tender mercy of God exhorts all, both ecclesiastics and secular persons, to stretch out helping hands to such converts if they are poor or in need at the time of their conversion. Bishops should exhort Christians to aid these converts and should themselves support them from the income of churches, as far as they can, and from what passes through their hands for the benefit of the poor, and they should defend them with fatherly solicitude from detraction and invective.
Since by the grace of baptism converts have been made fellow citizens with the saints and members of the household of God, and since regeneration in the spirit is of far greater worth than birth in the flesh, we determine by this edict that they should enjoy these privileges, liberties and immunities, of the cities and localities in which they are regenerated by holy baptism, which others obtain merely by reason of birth and origin. Let the priests who baptise them and those who receive them from the sacred font carefully instruct them, both before and after their baptism, in the articles of the faith and the precepts of the new law and the ceremonies of the catholic church. Both they and the bishops should strive that, at least for a long time, they do not mingle much with Jews or infidels lest, as occurs with convalescents from illness, a small occasion may make them fall back into their former perdition. Since experience shows that social communication between converts renders them weaker in our faith, and has been found to damage much their salvation, this holy synod exhorts local ordinaries to exercise care and zeal that they are married to born-Christians, in so far as this seems to promote an increase of the faith. Converts should be forbidden, under pain of severe penalties, to bury the dead according to the Jewish custom or to observe in any way the sabbath and other solemnities and rites of their old sect. Rather, they should frequent our churches and sermons, like other Catholics, and conform themselves in everything to Christian customs. Those who show contempt for the above should be delated to the diocesan bishops or inquisitors of heresy by their parish priests, or by others who are entrusted by law or ancient custom with inquiring into such matters, or by anyone else at all. Let them be so punished, with the aid of the secular arm if need be, as to give an example to others.
There should be careful inquiry into all these things in provincial councils and synods, and an opportune remedy should be applied not only to negligent bishops and priests but also to converts and infidels who scorn the above. If anyone, of whatever rank or status, shall encourage or defend such converts against being compelled to observe the Christian rite or anything else mentioned above, he shall incur the penalties promulgated against abettors of heretics. If converts fail to correct themselves after a canonical warning, and as Judaizers are found to have returned to their vomit, let proceedings be taken against them as against perfidious heretics in conformity with the enactments of the sacred canons. If there have been granted to Jews or infidels, or perhaps shall be granted to them in the future, any indults or privileges by any ecclesiastics or secular persons, of whatever status or dignity, even papal or imperial, which tend in any way to the detriment of the catholic faith, the Christian name or anything mentioned above, this holy synod decrees them quashed and annulled; the apostolic and synodal decrees and constitutions enacted about the above remaining in force. In order that the memory of this holy constitution may be perpetually retained and that nobody may be able to claim ignorance of it, the holy synod orders that it should be promulgated at least once a year during divine service in all cathedral and college churches and other holy places where the faithful gather in large numbers.
