Tainted Money?

QUESTION: Is  it a sin to let or sell a residence to a brewer or a cigar manufacturer or to one of their employees?

ANSWER:  It would be a good opportunity to show your disapproval by letting or selling your house at a sacrifice to some other person. But for me to say it is a sin to do otherwise, I am not prepared; for some one might raise the question whether the grocer would not sin in taking "tainted money" from the landlord, who has let or sold his house to a brewer or cigar-maker; and then whether it would not be wrong for the physician or minister to receive such money from the grocer, etc. etc., like "the house that Jack built." Human interests are so interlaced that there is no end to a boycott when once begun.

What Meats Should Christians Eat?

QUESTION: What meats should be eaten by Christians?

ANSWER: The word meat includes both vegetable and animal foods. There are some vegetables, such as tobacco, unfit for either saint or sinner to eat,  and  the extract of others, such as opium from the poppy, and alcoholic distillations from fruits and cereals, should not go into the mouth of any Christian. He is sure to eat healthy food if he limits himself to the clean animals enumerated. in Lev. II. But since Jesus abrogated the ceremonial law (Mark 7:19, American Revised Version), the Christian does not sin if he eats swine's flesh, clams, oysters, lobsters, eels, etc. It is thought that the superior longevity of the Jews arises from their observance of the Levitical Law which perfectly guards his beefsteak and mutton chops.
