Some Christians go further and find the whole concept of supporting a union contrary to their understanding of New Testament teachings. Unions typically use strong tactics, often including violent strikes, to force employers to concede to their demands. Three of the giants of the New Testament, John the Baptist, Paul and Peter, cast serious doubt on whether a Christian should be a part of this kind of organization. John the Baptist, in Luke 3:14, counseled believers to be content with their wages. Paul, in Colossians 3:22-24, told believers to work for their master as if they were working for the Lord. Peter, in 1 Peter 2:18-24, counseled Christians to suffer indignity at the hands of masters rather than retaliate. A Christian who understands that working for the employer is like working for the Lord will view most union tactics with grave concern. Since believers are warned by Paul in 2 Corinthians 6:14-17 against being "yoked together" with those who do not accept Biblical teaching, many find it impossible to join or financially support a labor union.
