What does this quote mean? "No one should fear to undertake any task in the name of our Saviour, if it is just and if the intention is purely for his holy service."

There is nothing to fear if your conscience is clear. If the task you are to undertake is just and you intend to do it for God, without any blasphemous reason, then God will know the truth and you can proceed to do the task in peace.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
