<p>15:15 <i>Yes, we are found false witnesses of God</i>- Paul expresses this in terms of breaking the Decalogue &quot;you shall not bear false witness&quot; because of the evident Judaist influences at work. We too should try to be all things to all men, reasoning in their terms as far as we can. If Paul had witnessed that God had raised Christ, but actually He had not raise Him, then Paul had witnessed falsely about God. Note that Paul doesn't say that he had taught a wrong message; his belief in the resurrection was a matter of personal witness. For he claimed to have met the risen Lord.</p><p><i>Because we witnessed of God that He raised up Christ, whom He did not raise if it is true that the dead are not raised</i>- The &quot;we&quot; refers to the apostles and all who had seen the risen Lord. Paul again sees their witness as united and not divided; and therefore no factions should develop following various apostles.</p>
