Conservative MP Jacob Rees-Mogg says he is "completely opposed" to abortion, including in cases of rape or incest.
The backbencher told ITV's Good Morning Britain that abortion was "morally indefensible".
"Life is sacrosanct and begins at the point of conception," he said.
Appearing on Good Morning Britain, he again distanced himself from leadership talk, before being asked for his views on same-sex marriage, which he opposes.
"I am a Catholic and I take the teachings of the Catholic Church seriously," he said.
"Marriage is a sacrament and the decision of what is a sacrament lies with the Church not with Parliament."
The Church's teachings on faith and morals were "authoritative", he said, but he added it was not for him to judge others.
However, he said he was completely opposed to abortion.
"With same-sex marriage, that is something that people are doing for themselves," he said.
"With abortion, it is something that is done to the unborn child. That is different."
