Natalism

Quiverfull is a theological position held by some conservative Christian couples belonging to various Christian denominations,[1] that sees children as a blessing from God.[2][3][4] It thus encourages procreation, abstaining from all forms of birth control (including natural family planning) and sterilization.[5][6]
Some have referred to the Quiverfull position as Providentialism,[7] while other sources have simply referred to it as a manifestation of natalism.[8][9]
