English to Spanish Art/Literary Religion 19th century text

Beware of supposing that sincerity alone can ever make up true zeal--that earnestness, however ignorant, makes a man a really zealous Christian in the sight of God. There is a generation in these days which makes an idol of what it is pleased to call “earnestness” in Christianity. These men will allow no fault to be found with an "earnest man". Whatever his theological opinions may be,--if he is an earnest man, that is enough for these people, and we are to ask no more. They tell you we should just ignore the minute points of doctrine and any questions about "words and names", about which Christians are not agreed. Is the man an earnest man? If he is, we ought to be satisfied. "Earnestness" in their eyes covers over a multitude of sins. I solemnly warn you to beware of this dubious doctrine. In the name of the Gospel, and in the name of the Bible, I enter my protest against the theory that mere earnestness can make a man a truly zealous and pious man in the sight of God.
