Jesus would not approve such practices. Anyone wishing to become a Christian would have to leave off such practices. But in order to remain in Christ's teachings you have to have accepted them in the first place.
The following are the words of John.
(2 John 9-11) . . .Everyone that pushes ahead and does not remain in the teaching of the Christ does not have God. He that does remain in this teaching is the one that has both the Father and the Son. 10 If anyone comes to YOU and does not bring this teaching, never receive him into YOUR homes or say a greeting to him. 11 For he that says a greeting to him is a sharer in his wicked works. . .
Jesus gave authority to his disciples and the book of Revelation gives details of how Jesus was not happy with any wrongdoing in the congregations.
(Revelation 2:2-5) . . .‘I know your deeds, and your labor and endurance, and that you cannot bear bad men, and that you put those to the test who say they are apostles, but they are not, and you found them liars. 3 You are also showing endurance, and you have borne up for my name’s sake and have not grown weary. 4 Nevertheless, I hold [this] against you, that you have left the love you had at first. 5 “‘Therefore remember from what you have fallen, and repent and do the former deeds. If you do not, I am coming to you, and I will remove your lampstand from its place, unless you repent.
