27-32: [27] Et post hoc exiit et vidit publicanum ...

et ait illi, Sequere me....

[30] Et murmurabant Pharisaei et Scribae eorum...

[31] et respondens Jesus dixit ad illos, Non egent qui sani sunt medico sed qui male habent.
The question respecting the disciples of John is turned against Marcion, as a recognition of the Baptist's mission.

If John had not prepared the way for Christ, if he had not actually baptized Him, if, in fact, there was that diversity between the two which Marcion assumed, no one would ever have thought of instituting a comparison between them or the conduct of their disciples.
