It seems that the answer is in the affirmative:
“The accursed perversity of heretics […] has so increased that now they exercise their wickedness not in secret, but manifest their error publicly, and win over the weak and simple-minded to their opinion. For this reason, We resolve to cast them, their defenders, and their receivers under anathema, and We forbid under anathema that any one presume to help heretics or to do business with heretics”-Third Lateran Council
“Canon 33. No one
shall pray in common with heretics and schismatics. …"-Council of Laodicea
“Moreover, we determine to subject to excommunication believers who receive, defend or support heretics……”-Fourth Lateran Council
“To know whom to avoid is a great means of saving our souls. […] Thus, the Church forbids the faithful to communicate with those unbelievers who have forsaken the faith by corrupting it, such as heretics, or by renouncing it, such as apostates.”-St Thomas Aquinas
