Love edifies

Chapter 8 of the first epistle to the Corinthians is more laudable. There are some word-plays to help readers memorize the passage. Below are two such poetic verses in Chapter 8.
Knowledge puffs up, but love builds up.
ἡ γνῶσις φυσιοῖ, ἡ δὲ ἀγάπη οἰκοδομεῖ. (1 Corinthians 8:1b)

yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist. ἀλλ' ἡμῖν
εἷς θεὸς ὁ πατήρ, ἐξ οὗ τὰ πάντα καὶ ἡμεῖς εἰς αὐτόν, καὶ
εἷς κύριος Ἰησοῦς Χριστός, δι' οὗ τὰ πάντα καὶ ἡμεῖς δι' αὐτοῦ. (1 Corinthians 8:6)
The issue was raised concerning the eating of meat offered to idols. Of course, Christians confess only one loving God. Other idols simply aren't any god. Therefore, for Christians, meat offered to idols is no different from ordinary meat. Even if those idols were really gods, Paul refuted the effectiveness of eating meat offered to idols.
Food will not commend us to God. We are no worse off if we do not eat, and no better off if we do(1 Corinthians 8:8).
Therefore, for Christians, eating meat offered to idols is not a problem. This is one of the many ways showing that knowing the truth will make us free. We will not be troubled by superstitions. We enjoy the freedom to eat any meat. That is how knowledge puffs us up!
Regrettably, in real life situation, nobody possesses complete knowledge. We must always take risks and make moral choices under the constrains of incomplete knowledge. Very often, we regret what we have chosen. We could have chosen better, have done better. How shall we improve our lots? How shall we approach a problem so as to minimize our regret? Paul suggests making love the motive of our choices and actions. Love edifies.
Go back to his famous example of eating meat offered to idols. Considering the possibility of hurting the conscience of brethren with a weaker faith, Christians should refrain from eating meat offered to idols. This is an act of charity. When our action is based on charity, we seldom err. Even if we err, we will not regret.
It is a pity that St. Paul had to pit knowledge against charity when he dealt with the Corinthian church. In Corinth, there might be Gnostics or some other Christians who prided themselves of their knowledge. However, without love, such knowledge is dead. That is why later, in chapter 13, St. Paul wrote an ode in praise of love.

My dear Advocate, I pray that we may all abide in Your love. Then we will make less mistakes. Amen.
