以下摘錄羅馬天主教廷針對稱義最有權威的，最後的闡述，就是在這個會議上，Council of Trent，這是羅馬教會針對馬丁路德的新教專門舉行的大公會。它的大公會的決議權柄甚至高過單個的教皇，而在這之後它的幾次教會公會中，再也沒有從新闡述稱義的問題。所以應該以下闡述是羅馬教會最正式的立場。

Council of Trent (1545 - 1563)

CANON 9:  "If any one saith, that by faith alone the impious is justified; in such wise as to mean, that nothing else is required to co-operate in order to the obtaining the grace of Justification, and that it is not in any way necessary, that he be prepared and disposed by the movement of his own will; let him be anathema." 

CANON 12:  "If any one shall say that justifying faith is nothing else than confidence in the divine mercy pardoning sins for Christ's sake, or that it is that confidence alone by which we are justified . . . let him be accursed"

Canon 14: "If any one saith, that man is truly absolved from his sins and justified, because that he assuredly believed himself absolved and justified; or, that no one is truly justified but he who believes himself justified; and that, by this faith alone, absolution and justification are effected; let him be anathema."

Canon 23: "lf any one saith, that a man once justified can sin no more, nor lose grace, and that therefore he that falls and sins was never truly justified; or, on the other hand, that he is able, during his whole life, to avoid all sins, even those that are venial,--except by a special privilege from God, as the Church holds in regard of the Blessed Virgin; let him be anathema."

我知道福音教會都聲稱接受“因信稱義”的教義，或者更確切地，是“唯獨因信稱義”的教義，但我的問題不是在問福音教會自己是不是相信唯獨因信稱義，而是問福音教會是不是把這個教義看成是如此機要，以至於凡是否認這個教義的系統，就不能被看成是真正的教會，就像凡是否認基督神性的組織不能被看成是真正的教會一樣？
