Often I put my trust in the deceitful words:
“This is the lawn of the Glenn!
The lawn of the Glenn! The lawn of the Glenn! I can do with it whatever I want!” However, the reality is that although I didn’t sow bindweed in the lawn, the process of eliminating it may do more harm than good to, “The lawn of the Glenn”!

R. How lovely is your dwelling place, Lord, mighty God!
Even the (pro-abortion politician) finds a home,

my king and my God!
Bishop Zurek, how can the Diocese of Amarillo humbly welcome the words of both Humanea Vitae and Laudato Si, which have been planted in us and are able to save our souls?
“Let them grow together until harvest;”
MT 13:30
Though it is true that sometimes it is lawful to tolerate a lesser moral evil in order to avoid a greater evil or in order to promote a greater good,” it is never lawful, even for the gravest reasons, to do evil that good may come of it (18)—in other words, to intend directly something which of its very nature contradicts the moral order, and which must therefore be judged unworthy of man, even though the intention is to protect or promote the welfare of an individual, of a family or of society in general.
from paragraph 14 of Humanae Vitae
It is difficult to make a general judgement about genetic modification (GM), whether vegetable or animal, medical or agricultural, since these vary greatly among themselves and call for specific considerations.
from paragraph 133 of Laudato Si
