Q. 1. What are the 9 ways that one can participate in the sins of another person?

A. 1. They are:

1.1. By counsel (to give advice, one's opinion or instructions.)

1.2. By command (to demand, to order, such as in the military.)

1.3. By consent (to give permission, to approve, to agree to.)

1.4. By provocation (to dare.)

1.5. By praise or flattery (to cheer, to applaud, to commend.)

1.6. By concealment (to hide the action, to cover-up.)

1.7. By partaking (to take part, to participate.)

1.8. By silence (by playing dumb, by remaining quiet.)

1.9. By defense of the ill done (to justify, to argue in favour.)

(Note: To participate in the sins of another person means that one is just as guilty of the sin as the one who committed them. For example, if you encourage someone to have an abortion, you are guilty of the sin of abortion.)
