My brothers, do not hold [views regarding] the faith of our glorious Lord Jesus Christ [i.e., as tenets of Christianity] which show favoritism toward [certain] persons.

Now if you people show special attention to the one wearing the fine clothing and say [to him], "You can sit here in this good seat," and to the poor person, "You stand over there," or "Sit on the floor by my feet,"read more.

In the same way [that Jesus was submissive], you wives should submit yourselves to your own husbands so that, even though they may not obey the [Gospel] message [they have heard] they may, without your talking [to them about it], be won by observing your godly and respectful behavior. Do not let your [adornment] be [the decorations] of the physical body, such as elaborate hair-dos, the wearing of golden [jewelry] and the wearing of [stunning] outfits.read more.
But [the kind of adornment you should display is] that of the inner person, with its enduring qualities of a meek and calm spirit, which are extremely valuable in God's eyes. For this is the way holy women in ancient times decorated themselves. Their hope was in God and they were known for being in subjection to their own husbands.
