never been to a date before and I am torn between doing this or this

it all started with my dad casually mentioning that I am single and that pretty much I am a decent human being, pretty much "ready to settle down" ergo an actually genuine good man, just 6'0, lots of cash saved into the bank, a house(pretty modest one), a car, did I mention single etc... so the women at the church somehow managed to convince dad to set up a date with one of the girls at the church(take this fucking parasite away from already), my expectation have never been lower but the potential to mess up this girl with facts is too much to simply just pass on, yet I want to be careful with this and know how to reject this call by simply creating excuses.

how do I approach this without these bitches bringing attention and pursue my ass? because I am not the type who have the patience for this bullcrap and I rather stay single, because rejecting a "gift from god" will be taken as an offense and a nuke to their egos(which doesn't sound bad but there will be consequences).

so guys, how should I do it? should I simply ignore I had a date and state that the existance of this girl doesn't matter to me and proceeding to go on with my life or should I take the chance to troll the shit out of this girl?.
