Christians are called "Saints"... What does that imply and what should "Not even be named" among them?

Matthew 5:27-28 You have heard that it was said to those of old, ‘You shall not commit adultery.’ 28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.

1 Corinthians 7:8 But I say to the unmarried and to the widows: It is good for them if they remain even as I ak;

1 Corinthians 7:9 but if they cannot exercise self-control, let them marry. For it is better to marry than to burn with passion.

1 Corinthians 7:2 Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband.

1 Corinthians 7:3 Let the husband render to his wife the affection due her, and likewise also the wife to her husband.

1 Corinthians 7:5 Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer; and come together again so that Satan does not tempt you because of your lack of self-control.
