What kind of girl did Nnaemeka's father want him to marry? Why?

Nnaemeka's father wants him to marry a girl
from the same tribe as him. More specifically, he wants his son to marry "the eldest
daughter of [their] neighbor." This girl is, he says, "a proper Christian" and
has received, at the home of a pastor, "all the training a wife could need." This girl
also "reads her Bible very fluently." Nnaemeka's father hopes that they can
"begin negotiations" for the marriage to take place as soon as possible.

Nnaemeka remembers this girl from his childhood. He remembers her as "an Amazon of
a girl who used to beat up all the boys, himself included." It doesn't seem to matter to
Nnaemeka's father that Nnaemeka doesn't love this girl. In fact, he seems surprised that his son
should think that this matters. When Nnaemeka tells his father that he doesn't love the girl,
his father responds with, "Why should you?" He tells his son that what one should look
for in a wife is not love, but "a good character and a Christian
background."

When Nnaemeka tells his father that the girl he wants to
marry is a teacher, his father tells him that "no Christian woman should teach." This
confirms that Nnaemeka's father wants him to marry a woman who conforms to very traditional,
very conservative ideas of what a good woman and wife should be. He wants for his son a wife who
will be subservient, reserved, and well-versed in Christian morality.
