Hi Well yes it is right to judge, but no it is not right to judge!! Do not judge someone for eating meat! Do not judge someone for new moons or Shabbat! But it does say if your brother offend you, tell him. So yes you can judge in some issue and in others you can not! So i answered sometimes, but it Yeshua said "judge not". But we have to protect our boundries! If it affects you then sure be critical, if it is just someone else and nothing to do with you then NO! Pray for them that they may come to repentance and learn not to be outside the Word of life. shalom
