2 All this it is pleasant for us to recall, and the more so because we see the fruits of it, and they are by no means small, still remaining. The greatest of all these fruits assuredly is that amongst the multitude of Catholics there is a love and an ardent zeal for that divine religion which your ancestors, in the first place from France, then from Ireland, and others from elsewhere, so religiously professed themselves and transmitted inviolate to their children. And if those children faithfully preserve this precious heritage it is easy for us to understand how much praise is due to your vigilance and activity, Venerable Brethren, and to the zeal of your clergy; for all work assiduously with one heart and one soul for the preservation and progress of the Catholic faith, and, to render this tribute to the truth, without meeting any disfavour or obstacle on the part of the laws of the British Empire. Accordingly, when out of appreciation for your common merits, we some years ago conferred the honour of the Roman purple upon the Archbishop of Quebec, it was our desire not only to acknowledge his personal qualities, but also to render a solemn homage to all Catholics in the country.
