There is a big difference between an honest mistake made in a moment of spiritual weakness and a willfull decision to disobey persistently the commandments of God. Those who deliberately choose to violate God's commandments or ignore the standards of the Church, even when promising themselves and others that someday they will be strong enough to repent, are stepping into a dangerously slippery slope upon which many have lost their spiritual footing.
Science. . . has become identified with a philosophy known as materialism or scientific naturalism. This philosophy insists that nature is all there is, or at least the only thing about which we can have any knowledge. It follows that nature had to do its own creating, and that the means of creation must have included any role for God.
