此段引文出自康熙阅毕罗马教宗特使嘉乐（Carlo Ambrogio Mezzabarba）呈递的教宗克雷芒十一世的通谕《自登基之日/自那一天》（Ex illa die）后说的话：「览此条约，只可说得西洋等小人如何言得中国之大理。况西洋等人无一通汉书者，说言议论，令人可笑者多。今见来臣条约，竟与和尚道士异端小教相同。彼此乱言者，莫过如此。以后不必西洋人在中国行教，禁止可也，免得多事。钦此。」（贾明子引文时特别略去了「条约」「乱言」的部分，是何动机呢？）
那么这则通谕到底是什么内容，居然引得康熙要禁教？让我们来看看。
首先上拉丁文文本的链接（第24页到第28页）：Confirmatio et innovatio Constitutionis incipientis: ex illa die a Clemente XI. in causa rituum ... Sinensium editae ...
I. The West calls Deus [God] the creator of Heaven, Earth, and everything in the universe. Since the word Deus does not sound right in the Chinese language, the Westerners in China and Chinese converts to Catholicism have used the term "Heavenly Lord" (Tiānzhǔ) for many years. From now on such terms as "Heaven" [Tiān] and "Shàngdì" should not be used: Deus should be addressed as the Lord of Heaven, Earth, and everything in the universe. The tablet that bears the Chinese words "Reverence for Heaven" should not be allowed to hang inside a Catholic church and should be immediately taken down if already there. 一、西方以「抖死」称呼天堂、地上与宇宙万物的创造者。由于在汉语中「抖死」听起来不对劲，所以在中国的西方人和皈依公教的中国人多年来以「天主」称呼之。从现在开始，「天」「上帝」都不准用了，只准称「抖死」为「天堂、地上和宇宙万物之主」。公教教堂中，凡是写了「敬天」的牌匾都不准再挂了，如果已经挂上了的也要马上摘下来。
II. The spring and autumn worship of Confucius, together with the worship of ancestors, is not allowed among Catholic converts. It is not allowed even though the converts appear in the ritual as bystanders, because to be a bystander in this ritual is as pagan as to participate in it actively. 二、皈依公教的人不准参加春秋两季的祭孔典礼和祭祖典礼。就算教徒只是作为旁观者参加这些仪式也不行，因为这么做跟积极参加此类活动同属异教之行。III. Chinese officials and successful candidates in the metropolitan, provincial, or prefectural examinations, if they have been converted to Roman Catholicism, are not allowed to worship in Confucian temples on the first and fifteenth days of each month. The same prohibition is applicable to all the Chinese Catholics who, as officials, have recently arrived at their posts or who, as students, have recently passed the metropolitan, provincial, or prefectural examinations. 三、如果中国的官员、进士、举人、生员皈依了罗马公教，那么他们就不准每月初一和十五进孔庙行礼。对于中国的公教教徒中那些新上任的官员或新科进士、举人、生员，这一规定同样适用。IV. No Chinese Catholics are allowed to worship ancestors in their familial temples. 四、中国的公教教徒不准在祠堂中祭拜祖先。V. Whether at home, in the cemetery, or during the time of a funeral, a Chinese Catholic is not allowed to perform the ritual of ancestor worship. He is not allowed to do so even if he is in company with non-Christians. Such a ritual is heathen in nature regardless of the circumstances. 五、不管是在家中、墓地还是在葬礼上，中国的公教教徒都不许祭拜祖先。就算公教教徒是跟非基督徒者在一起也不准有这类行为。不管在什么情况下，这种祭拜祖先的行为都是本质上没有信仰的表现。Despite the above decisions, I have made it clear that other Chinese customs and traditions that can in no way be interpreted as heathen in nature should be allowed to continue among Chinese converts. The way the Chinese manage their households or govern their country should by no means be interfered with. As to exactly what customs should or should not be allowed to continue, the papal legate in China will make the necessary decisions. In the absence of the papal legate, the responsibility of making such decisions should rest with the head of the China mission and the Bishop of China. In short, customs and traditions that are not contradictory to Roman Catholicism will be allowed, while those that are clearly contradictory to it will not be tolerated under any circumstances. 虽然我做出了如上决定，但我也明确说了对于其他的中国习俗和传统，只要不可被理解为是本质上没有信仰的表现，那么皈依公教的中国人就可以继续遵守之。中国人的齐家治国之道也不应被干涉。在中国的教宗使者对于公教教徒可以奉行哪些习俗、不可奉行哪些习俗有决定权；如果教宗使者不在，那么在中国的传教团其余成员以及中国主教有决定权。简而言之，（对中国的公教教徒而言，）跟罗马公教教义不矛盾的习俗和传统应被允许，但是那些明显与教义矛盾的习俗和传统无论如何都要禁绝。
哦，对了，知道罗马教廷到了什么时候才正式废除「禁止祭祖祭孔」的规定吗？答：1939年于《众所皆知》（Plane compertum est）通谕中正式允许祭祖祭孔。当然了，教廷不会承认《自登基之日/自那一天》（Ex illa die）搞错了，只会说「此一时彼一时也，现在的祭祖祭孔是世俗性活动而以前的祭祖祭孔是异教行为，所以公教教会以前没错、现在也没错」。哈，哈哈，哈哈哈，这死不认错的脾性我好像刚刚在哪见过啊。
