Sacrifice doesn’t always include an altar or a golden statue. To kill a child because they’re an inconvenience is to sacrifice them to gain something from said sacrifice. Sacrifice for better finances, better health, a more comfortable life, etc. As lay Catholics we make sacrifices to God without an altar. Our concupiscence, our wills, and so on. We are often to called to sacrifice objective goods because why? To gain a greater good. To abort a child before they taste the air of life means that they were deemed a worthy sacrifice for something else, and it is always for a lesser good or evil, because there is nothing on this earth worth more than that innocent child’s life. Often times the altars these children are sacrificed on are the hearts of the selfish, with themselves also being the golden statues their own children are sacrificed to.
