Was Paul ever accused of lying? I have always found it odd that Paul seems to have the need to emphasize the fact  that he isn't lying. It is almost like he is insecure about  his credibility. In Romans 3:7 he seems to imply that lying is acceptable if the glory of God is enhanced, I don't ever recall reading Jesus or any other Apostle having to lie to enhance the glory of God. Paul then wonders why someone might judge him as a sinner?

Ro. 9:1 I speak the truth in Christ — I am not lying,

1Ti. 2:7 And for this purpose I was appointed a herald and an apostle
— I am telling the truth, I am not lying — and a teacher of
the true faith to the Gentiles.

Ro. 3:7 Someone might argue, “If my falsehood enhances God’s
truthfulness and so increases his glory, why am I still
condemned as a sinner?”

My question is : Was Paul ever accused of lying directly or indirectly by someone?
For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
I speak the truth in Christ--I am not lying, my conscience confirms it in the Holy Spirit
rom 8:38-39 + rom 9:1

Paul is making a big claim, and is answering in his own head, &quot;How can I claim such a thing?&quot; And he is not appealing to scripture for this conviction, but
only to the Holy Spirit and his conscience. He is not saying he knows this to be true in a flash, like a revelation, but over time has become convinced of its truth.
Paul uses similar language in regard to women speaking in the
church.

&quot;I do not permit a woman to teach or to have authority over a man; she must be silent&quot;
1 Tim 2:12

Paul is not allowing something.  Elsewhere Paul says

&quot;To the married I give this command (not I, but the Lord): A wife must not separate from her husband.&quot;
1 Cor 7:10

Paul is saying he personally has authority as an apostle to give
guidance in the present situation.
Paul is not Jesus, and the guidance or views need to be balanced.
He says some were teaching from bad motives, and so where lying.

&quot;For the appeal we make does not spring from error or impure motives, nor are we trying to trick you.&quot;
1 Thess 2:3
&quot;It is true that some preach Christ out of envy and rivalry, but others out of goodwill.&quot;
Phil 1:15

So Paul's reference to &quot;lying&quot; is in the context of other teachers
who he would say are false teachers, which he would distinguish
himself from.
