Srimad Bhagavatam 4.2.30

4.2.30

ब्रह्म च ब्राह्मणांश्चैव यद्यूयं परिनिन्दथ । सेतुं विधारणं पुंसामत: पाषण्डमाश्रिता: ॥ ३० ॥

brahma ca brahmanams caiva yad yuyam parinindatha setum vidharanam pumsam atah pasandam asritah

brahma
the Vedas
ca
and
brahmanan
the brahmanas
ca
and
eva
certainly
yat
because
yuyam
you
parinindatha
blaspheme
setum
Vedic principles
vidharanam
holding
pumsam
of mankind
atah
therefore
pasandam
atheism
asritah
have taken shelter.

Bhrgu Muni continued: Since you blaspheme the Vedas and the brahmanas, who are followers of the Vedic principles, it is understood that you have already taken shelter of the doctrine of atheism.
